Harm from a harmful turtle

Bug bug (Eurygaster integriceps) - an insect, a family of moths, looks like its fellow bugs.

Bug harmful turtle biological features and control measures

The insect has an oval, wide, flattened body, the size of which reaches an adult individual in length up to 13 mm, width up to 7 mm. The color of the chitinous shell is light and dark brown with a yellow or grayish undertone, the design of the shell is dotted or oblong.

The wings of a harmful turtle, unlike some of its relatives, are very well developed. She is able to overcome distances from 50 to 200 km in search of the field. The mechanism of the oral apparatus is piercing-sucking.

With this shield pest agrotechnical and chemical control measures are applied.

Bug harmful turtle developmental phase and where it occurs

This type of pest lives one year. Only adult individuals winter. They begin to mate in the spring. Awakened from hibernation, looking for a field for reproduction and life. Having found a suitable place, no later than the end of May, in the crops of early winter crops, the females, after two weeks, begin to lay eggs.

Egg develops and grows depending on temperature, from 7 to 20 days. After ripening, the larvae begin to appear. Larvae grow from 20 days to two months. During this period, they have five stages of development and increase in size from 1.5 mm to 10 mm. The fifth stage of maturation of the larvae and fledging is called the stage of the imago and is possible only when feeding the larva with young shoots of grass.

The adults winter in the forest belt, away from the field and move to wintering areas during the winter harvest harvest until the end of October. The imago should accumulate the necessary fat reserves for winter, and if they are undernourished, and the crop has been harvested, they are fed in the litter on the field or along the road with seeds of wild trees and wild cereals.
In the spring the cycle repeats.

The population of harmful turtles is found in steppe forest belts of Russia (Lower Volga region, Stavropol and Krasnodar Krai, Rostov Oblast and other regions), Ukraine, European countries, and in some countries of Asia and North Africa.

What harm does a bug make a harmful bug?

The bug bug species is a dangerous insect and a threat to agricultural fields. After biting a young sprout, she deprives him of food. It ceases to develop further, dries out, the ear grows white.

If a pest bites a grain on a colossus, it becomes a poisoned enzyme that is injected when it bites to dissolve the grain to a liquid, nutritious state in which the pest can drink it. In this case, the plant does not die, but the grain will be of very low quality. It reduces the level of gluten, and when kneaded, the dough will be gray and liquid.

Grain contaminated from 3 to 5% is considered unsuitable.

Bug control measures harmful bug

For a good harvest you need to fight while still plowing the ground and the condition of the plant must be monitored from the very beginning of sowing. Bedbugs lay eggs on the leaves of plants, but adults can hide inside the ear.

Processing the field should be carried out twice - the first time from adult harmful bugs that survived the winter, the second - from their larvae. Larvae develop in good weather very quickly and if they do not have time to process the field on time, their numbers will quickly increase, the field will en massely hit adults, which are harder to fight. The damage to the crop will be irreparable.

Records of bugs on the field are maintained and, if their quantity standards are exceeded, insecticidal treatments should be carried out as a matter of urgency. Counting is per m2, processing should be carried out upon detection: 2 adults who survived winter, blooms and up to the milky state from 5 larvae of adults, with further growth - if 2 adult individuals are found per 1 m of area.

Preventive methods of struggle are:

  • Early harvesting - it does not allow the bugs to eat and prepare for wintering.
  • Early autumn ground cultivation, which contributes to the significant destruction of parasites.
  • In time carried out during the growing season insecticidal treatment.
  • Soil fertilizer with potassium and phosphorus.
  • Processing grain before sending it to storage in the barn.

How to get rid of the bug bug turtle quickly?

The most effective result when detecting overwintering imago is provided by a spraying method in two stages. The first is to fight adult adults and the second stage is to destroy their larvae. The second stage, always coincides with the formation of a young colossus.

Popular insecticide preparations:

  • Alpha Tzipi, EC
  • Volley, EC
  • Imidor, VRK
  • Karachar, KE
  • Tagore, KE
  • Tarzan, VE
  • Faskord, EC
  • Espero, COP
  • Tsunami, KE and others.

Before use, carefully read the instructions and remember the safety measures.

Description of the larvae

During its development, which takes about a month, the larva goes through five specific stages. It changes, sheds and begins to look more and more like an adult. After complete transformation, they pass from the stalks, on which the eggs were laid, to the neighboring ones and begin to actively eat them.

Description of the adult

Adult harmful bug looks very harmless and even pleasant-looking. She has a flat oval body up to twelve millimeters long. From above it is covered with a dense shell, covered with dots or lines. The color can range from gray to brown.

Favorite delicacy of these bugs is wheat. Sometimes they damage the planting of barley, oats. May spoil the stock of corn. When the harvesting is over, the settlements of bugs migrate to granaries and barns. Some go to the forests and bury themselves in the upper vegetation layer, about three centimeters.

This type of bedbugs does not harm the person directly. They do not bite or cause allergic reactions. If they hit the dwelling, you can simply throw them out the window.

Ways to fight

The first step is to carry out preventive work to prevent the appearance of a harmful turtle:

  • use planting material of varieties that are highly resistant to infestation by parasites,
  • fertilize the soil with potash and phosphate preparations,
  • regularly destroy weeds,
  • land near forest fields or areas with wild vegetation. They are gradually settled by the enemies of bugs: beetles, ants, spiders and birds,
  • on small plots in domestic conditions it is possible to fight a harmful turtle with the help of chickens. During the day, each individual can kill up to one and a half thousand bugs,
  • harvesting ripened crops should be timely. For this, direct combining should be applied.
If the infection with these insects did happen, it is urgent to take measures to destroy them.

How to deal with bedbugs yourself? For this purpose, specially designed chemicals are used - insecticides. You can use the tools "Decis", "Fastak", "Mavrik" and even a number of drugs of similar action. It is necessary to regularly change the compositions in order to avoid insects getting used to them.

Wrestling technology

It is necessary to begin to process plants when the spikes are gaining milky ripeness: it is at this very moment that the harmful turtle populates the fields and separate sections of the bugs. Spraying carried out at this time will have the greatest effect.

It is possible to carry out the treatment of contaminated planting areas either by air or in a local orientation on plants. The use of drugs of this type can not only get rid of this type of bedbugs, but also destroy a fairly large number of dangerous pests of field plants. In order to spray correctly and do not harm the plantings, it is necessary to strictly observe the dosage and precautions that are indicated on the package. For each drug, they will be individual.

About corn moth can be found in this article.

Knowing the external signs of the bug, the specifics of its behavior, the means and methods of dealing with it, it is quite possible to take timely measures for its prevention and destruction. And thanks to this, the proper quality of your harvest will be safely preserved.

How to recognize the enemy in person?

On the fields and gardens, several different species of bugs parasitize. Most often they are called the same - turtles. In fact, only the mischief bug is officially named. In addition to him, in the gardens often harm the green bug (stinker), beetroot and bug-shchitki.

The oval torso, covered with a grayish-brown pattern of irregularly shaped stripes and specks, has a bugs harmful turtle. Because of the similarity with the steppe turtles, the pest was named like this: it really resembles this reptile. Gardeners, this parasite is completely harmless, because it damages only grain crops.

Harm tortoise can bring in ornamental gardening, as it can damage the ears of cereals used in landscape design. Piercing the stalk at the base of the spike, the bugs are harmful turtle sucks the juices of the plant, because of which its development stops.

Young insects often feed on the ear itself. Piercing with the proboscis the skin of the grain, they actively feed. Because of the large number of insects, such a spikelet simply dies.

As they grow older, the parasites crawl on neighboring ears. The harm of insects to agriculture is aggravated by the fact that flour ground from damaged grain bugs is practically unsuitable for human consumption.

Feeding on the spikelets in the wax stage of ripeness, the parasites do not completely destroy them, but disrupt the formation of protein - gluten from the grain. The dough from low-gluten flour does not rise well, is gray in color and is unsuitable for baking bread and making pasta.

Garden pests

Stink bugs, or green bug, often found on tomatoes, eggplant, pumpkin and legumes. It also damages a significant amount of garden plants. A colony of stink bugs that settled on raspberries or currants can ruin a large part of the crop.

They feed on the juice of young shoots, forcing the branches to wither and twist, affect the leaves of plants. But most of all they are attracted by the sweet juice of ripening berries and fruits. Leaving their discharge on the surface with a pungent smell, insects often force the gardener to throw away the fruit, because it is not possible to get rid of the smell. Neither juice, nor jam or wine from such fruit will be edible.

Shchitniki and beet bugs mainly harm garden crops. The objects of their attacks are cruciferous leaves (cabbage, radishes, radish and daikon and other plants) and umbrella (carrots, dill, cilantro). Piercing the leaf trunk with a proboscis, the insect feeds on sap, and the plant fades.

Due to the fact that shields and beet bugs sometimes attack only sprouts or cabbage seedlings that have emerged from the soil, the damage caused by them can be very significant. For matured adult root vegetables or cabbage, they are dangerous only for large colonies that can significantly damage the leaves of cabbage or green crops. But even with a comparatively small number on the plot of garden bugs, their destruction is a necessity.

How to deal with bedbugs in the garden?

Despite the variety of bedbugs that damage garden and garden plants, the control measures against them are almost the same:

  • hand collecting insects
  • the use of toxic chemicals for destruction,
  • scaring.

If there are small children in the family who can pick and eat berries or other fruits in the garden, then it is best to use manual pest picking.

Sedentary insects can be easily shaken off in a bucket or jar. Collecting parasites from plants, you need to pay attention to the laying of their eggs. Usually they have the form of a cluster of rounded grains about 1 mm in size. The eggs are laid on the underside of the leaves. The newly hatched individuals are also located there. Larvae can be removed with part of the leaf where they sit. After all the pests are in the bucket, they should be burned.

Chemistry against pests

Against various pests, including bugs of different species, you can use the drug Aktara. The insecticide should be dissolved in water according to the manufacturer's instructions and spray the plants with a spray bottle or a knapsack sprayer. Processing should be done in calm weather in the morning or evening. The drug is easily washed off by rain, therefore, after precipitation, the treatment must be repeated.

Insecticide Karate Zeon is able to destroy bedbugs in 2-3 hours after spraying. Its protective effect can last up to 3 weeks. The amount of working solution needs to be prepared for single use according to the instruction. Store the finished solution can not.

It is possible to destroy bedbugs in the beds of tomatoes, on cabbage and other plants with a tried remedy - Karbofos. Its disadvantage is a strong smell and high toxicity. The drug is best treated plants at a young age, before setting fruit. Spraying should stop about 2-3 weeks before picking up the fruit.

How can you scare away bedbugs?

A plant with an unpleasant smell for bedbugs - tsimitsifug racemose, or black cohosh - can be planted in berry plantings. Decorative tassels of its inflorescences will decorate the garden and drown out the scent of plants on which the bug bug prefers to feed. A large number of tsimitsifugi in the garden does not pose a danger to children or domestic animals, so you can safely use the plant as protection against parasites.

Garden crops can be sprayed with an infusion of onion peel: 200 g brew 1 liter of boiling water and insist. Infusion diluted in 10 liters of water and spray this plant with liquid. Onion peel can be replaced with the same amount of mustard powder. A strong smell will mask the aromas appealing to bedbugs and help preserve the harvest.

To prevent pests from appearing at their summer cottage, in the fall it is imperative to remove the tops and plant residues. It is in them that the insects winter, which with the onset of the first warm days begin to harm the garden.

Features of the species, habitat

Bug harmful turtle belongs to the family of shushnikov-turtles. This name was given to this species for appearance, since the body of the insect looks like a little turtle, and the relief and color of the elytrice resemble shell. The size of an adult individual varies from 10 to 15 mm in length.

In everyday life, this species is classified as a grain bug. The popular name is due to the gastronomic preferences of the parasite. A bug bug photo is presented below.

Bugs of a turtle belong to the order of hemiptera and have two pairs of wings. Pests fly perfectly and move easily between feed bases.

In search of food, the bug turtles can overcome tremendous distances, migrating not only between fields, but also administrative areas.

Parasites show their activity with the onset of stable heat, when the temperature reaches 15 degrees above zero. The sex of the future insect does not play a role in the intensity of feeding of the larvae. During this period, overwintered individuals begin to actively eat winter varieties of cereals. The bug bug is especially common in wheat, he likes young succulent stems.

After the larvae that have left wintering pupate, a period of intensive mating and laying of eggs begins.Female bugs of turtles lay from 140 to 250 eggs for a short favorable period, which is just over a month.

The harmful bug bug has 14 eggs in the abdomen, which allows her to lay 14 eggs at the same time.

Under favorable climatic conditions, an embryo develops within a week, after which a larva hatches. Its dimensions do not exceed 1.4-1.6 mm. From the moment of appearance and until reaching the mature form, the larva has to go through 5 stages of development. With each phase, the appearance of the young individual more and more resembles an adult insect.

During the growth period, the larvae actively feed and accumulate the mass necessary for transformation into the next stage. It doesn't matter what the bug bug eats, whether it is corn or wheat, but its mouth apparatus does not allow eating solid food. In the early stages of development, the larvae make punctures in the stems of plants and suck its juices. Older individuals parasitize on the seeds of cereal crops and in order to liquefy hardened grains they inject a special enzyme.

Habitat grain bug distributed from the steppe zone to the forest-steppe. The insect is moderately thermophilic, so in the hot months, when the temperature rises to 30-35 degrees, it moves from the fields to the forest edges, parks and squares.

During this period, the pests are frequent guests in homestead land and summer houses, where the bugs are harmful turtle damages corn crops or other succulent plants. By the time the harvest begins, the insects are gaining enough fat mass for a successful wintering and with the onset of cold weather go into a sleeping state.

Danger to humans and animals, harm to agriculture

Despite the fact that the mouth apparatus of all the bugs has the same structure, not every species parasitizes animals during feeding. Bug harmful turtle can not cause physical harm to a person or another member of the warm-blooded, despite their formidable appearance.

Sometimes pests accidentally fly into a dwelling, but they do not carry any threat. But taking the shield with bare hands is not recommended, as it releases a special strong-smelling enzyme to scare away birds of prey. Therefore, the insect is often referred to as a bug stinker.

Shchitniki-turtles harm agricultural plants. Their favorite foods are barley, maize or other valuable cereal crops. Most often parasitic bug bug on wheat. Sometimes during the period of mass reproduction, pests reduce yields by 15%, causing severe economic damage not only to agricultural organizations, but also to private horticulture and household plots.

The bug bug bugs feed on the sap of the plant, for this it pierces the stem or spike and ferments the contents internally, and then sucks it out. Weathered crops lag far behind in growth and do not gain the necessary ripeness.

Grain damaged by a bedbug loses its commodity value and is practically unsuitable for making flour. The product obtained from the grains infected with enzymes is not suitable for baking, it has a gray color and a strong viscosity when kneading dough. To get high-quality wheat bread, flour should not contain damaged grains.

The main signs of damage to crops bedbug harmful bug are:

  • withering of young shoots in the focus of infection,
  • white color of ears and shoots
  • the presence on the mature grains of microscopic chips and points at the bite points of the bug.

Bug harmful turtle prefers to eat the most valuable and expensive types of crops.

Due to its high mobility, the insect very quickly populates large areas, increasing its number and without special protection measures is able to destroy crops on large areas.

Fighting bug bug

There are two main ways to deal with parasitic bugs harmful turtle:

  1. Chemical, when insects are eliminated with the help of potent insecticides.
  2. Biological, in which parasitic individuals are destroyed by other living creatures: smaller insects or fungi.

An additional measure of protection against pests are preventive measures and the creation of adverse conditions for the life and reproduction of parasites.

The most effective drugs to combat the bug-bugs are:

  • Bassoon - intestinal insecticide from the group of synthetic pyrethroids causes a massive death of adults and larvae, which cures infected areas and allows plants to develop normally.
  • Alpha tsipi - synthetic pyrethroid, affecting the larvae in any stage. Effective for the treatment of large areas, can simultaneously cure several hectares of cereal crops.
  • Aktara - an insecticide from the group of neonicotinoids, which after an hour after treatment slows down the vital activity of the parasites, the bug bug stops feeding and a day later most of the population dies.

The biological methods of combating parasites include exposure to spores of various fungi that lead to infection and death. This method is environmentally friendly. Effective method of distribution in the habitat of turtle-insects of other predatory insects, using bugs as a food resource.

To get rid of the bug on the plots you can with the help of some breeds of chickens, each of which is able to peck up to 100 larvae per day. As a comprehensive measure, use early harvest and use special varieties of grass, resistant to parasites.

Bugs are harmful turtles - serious pests that can destroy entire wheat fields of expensive solid varieties. For successful pest control it is necessary to take a whole range of measures aimed not only at exterminating insects, but also at creating unfavorable conditions for their development.

Bug harmful turtle: description, photo and measures to combat insects

Bug harmful turtle does not settle in houses or country houses, it damages crops in the fields and in barns, where the latter can be stored. Growing up grain, it is possible to notice that qualitative characteristics of grain changed. Various influences can spoil the culture, but it is especially bug that can cause serious damage, which will be discussed later in the article.

Bug of the genus of turtles

Different types of bugs can be easily distinguished from other parasitic individuals. These insects have a body shape that is adapted to the conditions in which they inhabit. Some insects have a flat body, which becomes rounded after the bug is saturated with blood.

Individuals from the family of earth shields and desert bugs have a spherical body shape. Rare species are also rod-shaped. There are bugs, which in appearance very much resemble small turtles, they are called - harmful turtles. The bugs are hemiptera insects, which were given this name because of the structural features of the front wings. All species of bugs have three pairs of legs that help them move, hold their prey and swim in the water. Each pair of legs developed in varying degrees.

The length of the turtle beetle can be from 10 to 13 mm, the width is usually equal to 6.8-8.8 mm. The body of the insect is convex and oval, covered over with a chitinous shield. Color can vary from black to sand beige.

Life cycle features

The bug is a flying insect. When the spring comes warm, and the thermometer rises above 14-16 ° C, these pests wake up after wintering. Winter they wait in the gardens and forest plantings, under the leaves that have fallen. It is noteworthy that they can spend the winter in a place that is located at a distance of 180-195 km from the fields where they feed in the summer. The direction of flight of these insects depends mainly on the direction of the wind. The phase of laying eggs in bugs, turtles occurs about one and a half weeks after their flight to the field. Insect eggs are laid on young seedlings of grain crops, dry, and weeds. During one season, an adult female can make up to 15 clutches of 14 eggs each.

Bedbugs develop about 35 days, and live on average 10-11 months. Interestingly, food is the same in adults and in young individuals. So such insects are able to destroy large areas of planted areas.

Signs and harm

To determine the presence of bug turtles on wheat or other grain crops can be on a number of grounds:

  • In cases where the beetles have not yet scattered across the field, one can see many wilted young shoots of culture in one area.
  • Spikes that have been affected by pests have distinctive features. They are deformed and gain a whitish hue.
  • The grain itself may change color. Also on it, if you look closely, there will be visible marks after insect bites and weak punctures.
Insects are able to choose those vegetable crops that have high nutritional value. Such plants quickly grow, and also contain a lot of nutritious juice in their stalk.

Important! This bug is absolutely harmless for humans. After his bite, a mild allergic reaction may occur, but this is the maximum. So if such an insect is noticed in a house or other living space, you should not take any additional measures to destroy the bug, simply release it through the window.

After the beetle is saturated with the juice of a grain crop, the grain will already be completely unsuitable for further use. This is due to the fact that in the saliva of the beetle of a harmful bug there is a special enzyme that affects the chemical composition of the food product.

It is almost impossible to distinguish the affected flour from the high-quality dry product, since the enzymes in the dry state lose their quality. But as soon as the flour begins to knead the dough, the substance in the humid environment will start working again and instantly change both the texture and the color of the product. The economic threshold for bugs of winter bugs that overwinter:

  • at the tillering stage - 1-2 individuals per 1 sq. m. m
  • in the period of earing and flowering - 5-10 larvae per 1 square. m
  • phase of milky ripeness - 5-6 insects per 1 square. m

The threshold may vary depending on the value of the wheat product. Harmful turtles can affect not only wheat, but also oats, barley and even corn. When the growing season comes to an end, the insects move to where the grain is stored, for example, in barns. Part of the bugs are sent to winter, burrowing into the ground, waiting for spring heat. May beetles, a bear, a mole rat, a locust, voles, hares, moths, tsikadki, mice, shrews, moles, Colorado beetles do great harm.

Pest Control

To know what measures to deal with bugbugs can be applied is extremely important and even necessary:

  • It is possible to significantly reduce the amount of food for insects and at the same time protect the high quality of grain through the timely harvesting of grain, quick threshing, and direct combining.
  • Weed control and stubbling can also help.
  • We should not forget about fertilizer fields, it is especially important to use complex mineral compositions of phosphorus and potassium.
  • At the current time there are special preparations - insecticides, which can be sprayed fields. These include: Decis, Fastak, Mavrik, Arrivo, Fury, Fosbecid, etc.

Important! It is recommended to alternate preparations intended to control the bugs of the harmful bug in order to avoid adaptation of adult beetles and larvae to the poison.

Prevention rules

In order to preserve the crop and avoid increasing the insect population by the next season, the fight against the bug will have to start with preventive measures. For this it is recommended:

  • Conduct fertilizer soil mineral complexes that contain potassium and phosphorus.
  • In the shortest time to harvest. If he stays on the field for a long time, he may be hit by parasites.
  • Destruction of weed plants on the foliage of which can be eggs of bugs.
  • Additional processing of grain, cleaning it from debris and dirt, drying.
Experienced farmers recommend planting cereal crops in those areas that are surrounded by planting or forest belt. Trees will become an insurmountable obstacle for this type of insect and will force them to look for another site for their settlement. In addition, “enemies” of turtles beetles live in the forest plantations: spiders, birds, ants.

By adhering to a number of recommendations, the farmer will be able to provide a full grain crop, not allowing pests to develop their populations on crops.

Bug turtle - a way of life and effective methods of struggle

Bug turtle is active in the period of ripening of cereals. At the same time he is able to destroy both industrial and ornamental plants. Therefore, the main methods of struggle should know and be able to apply every gardener and gardener, as well as those whose activities are connected in one way or another with agriculture.

Bug turtle destroys young shoots during their growth

External signs

As they say, the enemy must be known in person, so the external characteristics of this parasite should be considered first.

As seen in the photo above, the bug bug has a flat oval body. Its color may be different. There are individuals of a rich gray color, as well as a shade of brown and yellow. Its shell is quite hard, it has a pattern in the form of strips and dots. The pattern is clearly visible, as it has a lighter shade than the shell itself - light green or silver.

The head compared to the body of small size, approximately half its size. The wings are rounded in shape and very well developed.

In search of food, this insect can fly about 200 km. The bug bug eats on plants sap, the capillaries of which it bites through with a piercing-sucking mouth organ. Stems begin to dry out and eventually shoots die.

The eggs of these parasites are small and painted white or light green. The structure is translucent. The larvae appear about a week after laying, and after five stages of maturation turn into an adult.

Habitats and features of existence

Cereals are the main source of food for bugs of turtles. Numerous colonies of these insects are capable of causing enormous damage to the land and destroying a fairly large crop.

Parasites overwinter in the forest, where the fallen leaves or perennial weeds serve as a temporary shelter. If they find a storehouse with wheat nearby, they will surely move there. In such barns, it is very comfortable for them to winter - cozy and satisfying.

With the onset of spring, when the air temperature rises to the mark of + 15 ° C, hordes of bedbugs fly in search of food. Most often they stop in the fields where early winter crops have already sprouted. Such places are ideal for living and mating.

Females lay eggs directly on the plant stems within two weeks after mating. After 7 days, young appear from them, which immediately begins to suck the juice from the young shoots.

The female can lay up to 40 eggs at a time.

Attention! The number of bedbugs is growing very quickly, and they can completely destroy the crop in the area where they settled.

As mentioned above, the larvae go through five stages of maturation and the entire period lasts about a month.At each stage, the bugs molt and gradually acquire the characteristic color and shape of the body of an adult insect. At each new stage, the parasite increases in size and therefore the space on the stem becomes smaller. Thus, they are distributed to neighboring spikelets and after a short period of time they fill the entire field.

After a similar feast, the plant quickly fades.

Signs of appearance

It is not difficult to determine that a mischievous bug has appeared on your grounds. The following are the main signs by which you can establish the presence of this parasite:

  • if the bugs have not yet spread out over the entire field, then on a certain part of it the mass wilting of shoots will be observed,
  • damaged ears will have characteristic differences: whitish tint and deformation,
  • the grain changes color, bite marks are noticeable on it, and there are punctures.

Oddly enough, but this insect chooses those plants that are of high nutritional value. These cultures grow rapidly and contain large amounts of juice in the stem.

Important! Bug bug is completely harmless to humans. Its bite can cause a slight allergic reaction, but no more. Therefore, having found it in the apartment, you should not take any measures for destruction. Simply throw it out the window.

After the bug is saturated with the sap of the plant, its grains become completely unsuitable for consumption. This is due to the presence of a special enzyme in the insect's saliva, which affects the chemical composition of the product. This substance enters the stem when piercing the proboscis and quickly spreads to the ear.

Infected flour can not be distinguished from the quality, as in a dry environment, the enzymes lose their quality. But it is worth kneading the dough, as the substance begins to work again and immediately changes the consistency and color of the product.

Tip! If you notice that after kneading the dough turned dark gray and has acquired a viscous structure, then it should be thrown away, just like the flour remaining in the bag.

How to get rid of pests?

There are methods that can prevent the appearance of bugs of turtles:

  • ripened crops must be harvested in time with a combine,
  • it is necessary to destroy wild-growing weeds in time, but at the same time to preserve the forest belt located along the perimeter of the site, and also not to destroy the plants on which the bugs of turtles live,
  • fertilize the fields with products that contain phosphorus and potassium,
  • for planting use varieties of crops that are resistant to these and other pests.

When insects appear, radical steps should be taken to destroy them. In this case, effective will be drugs that include chemicals targeted action.

Important! Treatment should be carried out during the milky ripeness of the ear, when the parasites are just beginning to colonize it. Only in this case, you will achieve the best effect.

Insecticide characterized by a wide range of effects. They are treated with plants using a knapsack sprayer. It is necessary to spray means in windless weather in the morning and in the evening. It should not be allowed to hit the neighboring cultures.

Tip! Watch the weather forecast, as the drug is not recommended to use if rain is expected in the coming hours.

After using the product, the bugs stop eating and soon die.

Karate Zeon

Karate Zeon is a water suspension that has a quick effect on pests. At low dosages, this drug is able to destroy a high percentage of insects. It differs from other means by repellent action, therefore it is absolutely harmless to bees.

The period of protective action depends on weather conditions and can reach 3 weeks. Bedbugs die 2-3 hours after treatment. The prepared solution can not be stored, it must be used on the day of preparation.

The tool destroys adults, as well as adults and larvae of older ages.

Spraying can be carried out from the air or locally. Both the first and second insecticide will help you get rid of not only the bugs of turtles, but also from other pests.

At the first signs of the appearance of bug turtles on your site, you must immediately take measures to destroy them. Any delay on your part can be disastrous for the entire crop.

The insect has an oval, wide, flattened body, the size of which reaches an adult individual in length up to 13 mm, width up to 7 mm. The color of the chitinous shell is light and dark brown with a yellow or grayish undertone, the design of the shell is dotted or oblong.

The wings of a harmful turtle, unlike some of its relatives, are very well developed. She is able to overcome distances from 50 to 200 km in search of the field. The mechanism of the oral apparatus is piercing-sucking.

With this shield pest agrotechnical and chemical control measures are applied.

What eats bug bug turtle?

The turtle eats mainly valuable wheat varieties - spring and winter, less often - rye and barley, extremely rarely - corn and millet.

For a good harvest you need to fight while still plowing the ground and the condition of the plant must be monitored from the very beginning of sowing. Bedbugs lay eggs on the leaves of plants, but adults can hide inside the ear.

Processing the field should be carried out twice - the first time from adult harmful bugs that survived the winter, the second - from their larvae. Larvae develop in good weather very quickly and if they do not have time to process the field on time, their numbers will quickly increase, the field will en massely hit adults, which are harder to fight. The damage to the crop will be irreparable.

Records of bugs on the field are maintained and, if their quantity standards are exceeded, insecticidal treatments should be carried out as a matter of urgency. Counting is per m2, processing should be carried out upon detection: 2 adults who survived winter, blooms and up to the milky state from 5 larvae of adults, with further growth - if 2 adult individuals are found per 1 m of area.

Preventive methods of struggle are:

  • Early harvesting - it does not allow the bugs to eat and prepare for wintering.
  • Early autumn ground cultivation, which contributes to the significant destruction of parasites.
  • In time carried out during the growing season insecticidal treatment.
  • Soil fertilizer with potassium and phosphorus.
  • Processing grain before sending it to storage in the barn.

Features of the development of harmful turtle

Bedbugs hibernate under leaf litter. Wintering ends at a temperature of 15? С. It is then that the insects fly over to the next crops (most often it is winter crops) and feed on them. At this time, the pairing of bugs, turtles.

Female bugs are very prolific, can lay up to 150 eggs at a time. One clutch contains up to 40 green eggs, usually they are on the bottom of the sheet. Larvae occur on the 7th or 10th day.

At this time there is a sharp jump in the number of insects. It is at this stage that bugs are most vulnerable to insecticides. Prompt measures taken will avoid serious consequences.

In 20-30 days, the larvae become adult insects, gradually settling all neighboring plants.

Factors contributing to the increase in the number of harmful turtles:

  • the presence of a large number of weeds, in particular - cereals,
  • delayed harvesting of crops,
  • favorable wintering conditions, warm spring.

Bug harmful turtle, egg-laying and hatched larvae

Wheat Damage Caused by a Bedbug Harmful Bug

Natural decrease in the number of bugs-turtles

Many factors affect the decline in the number of harmful turtles. A special place among them is occupied by the natural enemies of these insects. The main parasite of the bug bug is the telenomus, an insect that lays its eggs in the pest. The infected eggs of noxious turtles change their color to black or blue-black.

Another natural enemy of the noxious turtles is the Phase Flies. Adult flies lay their eggs on the body of the bug. The hatched larvae penetrate under the shell of the insect and feed on it until its death. There are other predatory insects and spiders that destroy the bugs and turtles at different stages of development.

Did you know? Some research institutes and special biofactories specialize in protecting crops from insect pests through the use of entomophages (insects that eat other insects).

Telenomusi or fly-phase pre-grown in laboratory conditions and at the right time they are released in the field. Thus, crops can be protected without the use of toxic chemicals. However, such procedures have many subtleties and are carried out by specialists.

This area is called biological plant protection and has been actively developing in recent years.

Protecting plants from harmful turtles

The main method of dealing with a harmful bug is still chemical treatment. It is better to use insecticides of systemic action, they penetrate into all organs and tissues of the plant, the damage of the bug occurs during its feeding.

Insecticides against a harmful bug are presented in wide assortment:

  • Alpha Tzipi, KE.
  • Caesar, KE.
  • Tsunami, KE.
  • Bassoon, KE.
  • Faskord, KE.
  • Fastak, KE.
  • Alterre, KE.
  • Alphachance, EC.
  • Fatrin, KE and many others.

Processing must be carried out twice. The first one is against bugs that survived the winter, the second one is against the hatched larvae.

Important! When using chemical insecticides, follow the norms of consumption and methods of use of the drugs indicated on the package. Pay sufficient attention to safety.

It is possible to choose the necessary chemical insecticide against the bug of the harmful bug using the List of pesticides and agrochemicals permitted for use on the territory of the Russian Federation. The handbook is published annually and contains a full list of plant protection products officially registered in Russia.

Cover of the list of pesticides and agrochemicals (can be found on the Internet)

I used Fatrin and Aktar (there is a reference book), the result I was completely satisfied. The most important thing is not to miss the moment of hatching of the larvae and make processing in time.

Other ways to deal with a bug

There are more environmentally friendly insect pests. So the microbiological drug Bauverin based on Beauveria bassiana causes a disease called “white muscardine” in insects.

The fungus, getting into the body of the insect, not only poisons it with its toxins, but also germinates through it. The insect is enveloped in the white mycelium of the fungus and soon dies. Tests of Boverin against the bug of the harmful bug were very effective (Suzdalskaya M.V.

White Muskardina harmful Turtle // Proceedings of VIZR. 1958. -F. 9.-S. 341-361).

In addition to the use of special tools, it is important to follow simple rules: maintaining the cleanliness of forest belts, timely harvesting, and adhering to the processing time.

Bowerin, of course, difficult to get, but it works well. For humans, it is non-toxic and safe. No need to use hazardous chemicals against the bug

: the bug bug bugs eat wheat

Bedbugs are frequent inhabitants of gardens, vegetable gardens and even living spaces. Very often, their presence brings inconvenience and requires special measures. Some bedbugs have well-defined taste preferences. So, for example, a green bug prefers to eat exclusively raspberries. Features of water strider bugs Always, while resting near water bodies, we observe small insects with long legs, which move easily along the surface of the water. These are vodomer bugs, which are significantly different from other members of their squad. Photo Italian bugs Italian bugs (lat. Graphosoma lineatum) or striped graphosome or striped shield is well recognizable due to its appearance. Italian this bug was named due to the similarity of its colors with the shape of the Vatican Guardsmen. Summer residents call it a tiger-bug, a bed-bug. The destruction of the wood bug of the shield plant is a very common type of bug. It is often found on the territory of Russia and other countries, prefers to settle near water bodies, sometimes flies into houses and apartments. What the bug looks like Bugs of different families differ significantly from each other. Some people harm agricultural crops (mischief bug, Italian bug, berry bug, pear lace), others are inhabitants of a person’s home, which causes a lot of inconvenience (bed bugs). Some bugs have successfully mastered the aquatic environment, for example, bugs of the gladeous family (Notonecta).

The bug insect bug (Eurygaster integriceps) is a dangerous pest of grain crops, showing maximum activity during their growth and maturation. Often you can find this insect on young shoots of wheat or on the ears in the stage of wax maturity.

Although this bug is mainly the enemy of large industrialists, it often damages decorative cereals, which is why it is useful to know the nuances of dealing with it to everyone who is somehow connected with agriculture.

What a bug bug looks like

The bug, an oval with a flat calf, a bug, which photo is presented below, is quite recognizable:

Although the insect can have several variants of coloring: gray, brown-gray, yellowish-gray, it differs from other pests by a very dense protective shield-shell, which is covered with patterns - dots or lines. Most often these patterns are whitish, but sometimes they can have a light green or silver shade.

The pronotum of the bug is approximately twice the size of the head, the wings are rounded. This bug flies beautifully and in search of food can cover distances up to 200 km!

The oral apparatus is piercing-sucking, with its help the pest bites through the stalks of wheat, sucking the juice from the capillaries of the plant.

The pictures of the bug eggs are small, round and greenish in color:

After 7-10 days after oviposition, the larvae appear, which go through 5 stages of development and gradually approach the appearance of an adult individual. The photo shows the bug bug bug in the stage of the 1st instar larvae:

“Never before encountered such a pest. But recently they planted a new section of the field, right near the meadow. It can be seen from there these turtles and flew. Pretty big bugs, colorful, fly well. After them, the wheat is absolutely not suitable for grinding, the dough is sticky ... now we are actively trying to bring them out, but so far nothing helps. The bug on wheat is a real attack for the harvest. ”

Nikita Antonovich, Krasnograd

Pest lifestyle

Bug turtle is a great threat to crops - they are his source of food.In winter, the bugs are looking for a new temporary place of residence, moving under the leaf litter in the forest or stopping on perennial weeds. Sometimes barns or wheat bins can serve as wintering grounds.

With the onset of spring heat (10-15 degrees), bugs fly in search of early winter crops. As soon as they find a place suitable for feeding and living, the mating of the males and females occurs massively. 10-15 days after that, each female of the harmful turtle lays 30-40 eggs, mainly on the leaves of the plant.

After 7-10 days, new larvae appear, which feed in the same way as adult insects. Due to the sharp increase in the number of bugs during their reproduction, they can destroy a serious part and even completely the entire crop in a certain area.

It is also useful to read: Details of life bugs water strider

The full cycle of transformation of the larva into imago takes 20-30 days, during which the insect goes through five stages of maturation and molting, each time becoming more and more like an adult bug. If the larvae are most often found on the plant where they were born, then after turning into an imago, new bugs of the turtle begin to actively populate the neighboring spikes and multiply, gradually covering huge areas.

How do bugs and turtles harm people?

Directly to humans, the bug a harmful bug is harmless. He does not bite, so even if the insect was in the house, the easiest way to throw it out the window.

Before you get rid of the bugs of turtles, you must first detect them. Listed below are signs indicating the spoilage of grain by the bug of the bug;

  • the mass withering of young shoots that occurs in a certain zone (if the bugs have not yet inhabited the whole field),
  • belkolosost or deformation of the ear, changing its original shape,
  • on the ripened ear, there are noticeable chipping of the grain, a change in its color, or traces (points) from the bug bite.

Scientists have found that the bugs are harmful turtle prefers to eat the most valuable for human grades of crops, powerful and able to grow quickly and produce a large number of juices. The pest is really capable of causing very significant damage.

In the grain on which the bug bugs parasitized, the amount of gluten will be significantly reduced.

The fact is that the bug’s saliva contains a special enzyme that significantly changes the chemical composition of the product and makes it unsuitable for use.

Piercing the stem of the plant with its long proboscis, the bug introduces an enzymatic fluid into the capillary, which then spreads along the upper part of the stem and the spike.

The most interesting thing is that the flour ground from grains of damaged ears looks the same as that made from a healthy ear. Here are the properties, it differs far from the best.

After kneading the dough, the enzymes start working again. The dough becomes viscous and viscous, becomes dark gray. Naturally, such flour cannot be used for cooking or baking.

Harmful bug bug

The bug flies well and can travel long distances. This insect is completely harmless for a person; it cannot bite through the skin and cause allergies. If such a bug was accidentally in the apartment, you can simply throw it away.

Thanks to the device of the mouth apparatus, the bug of a harmful bug makes injections into the stem of the plant, feeding on its juices. Depending on the phase of development of the plant, in which the damage was done, there is a slowdown in growth, a delay in flowering and a spike. Making an injection into the grain, the bug introduces its enzymes into it along with the saliva, which worsens the baking properties of the flour. Bug turtle harms not only industrial crops, but also plantings of decorative cereals on a personal plot.

Important! It is possible to detect the bug bug on the foci, where the young shoots wither, the ear shape changes, the grains are deformed. These insects prefer the most powerful plants that can produce juices in large quantities.

Bug bug Turtle bug Bug harmful bug Bedbugs bug

Almost all types of bugs that live on our planet are parasites. Many species parasitize animals and prefer blood, but some feed on the sap of young plants.

The bug bug is not a bloodthirsty species, but is the worst enemy of man and causes enormous harm to his activities.

Bedbugs are most susceptible to cereal crops, and if effective measures to protect the crop are not taken in time, the economic damage will be noticeable.

The bug is a harmful turtle: species and control measures

A small oval-shaped bug bug is considered one of the most dangerous pests of agriculture. Parasitic on cereals, large colonies of these insects can significantly reduce the quantity and quality of the crop.

Well-groomed garden and field crops are much richer compared to their wild counterparts, because they are provided with a sufficient amount of water and fertilizer and destroy weeds. Therefore, the only thing that remains for the owners of cultivated crops is to fight pests that want to feast on succulent plants.

Bug harmful turtle: methods of struggle

Since the development of agriculture, man has constantly come across insect species such as bedbugs. They harm the harvest of certain crops.

In our time, the most dangerous enemy of the agrarians is the bug bed bug, which over the past thirty years has significantly increased its population and spread to the steppe and forest-steppe territories of Russia and Ukraine, to a number of countries in Asia, North Africa and many European states.

Bug harmful turtle

Bug bug life cycle

Bug turtle - a flying insect, the size of 10-13 mm. It has a flat oval shape, white, light brown or light green color. Detachment - hemiptera, family - shchashnik-bug.

At the onset of spring warming, when the temperature of the air rises above 12-15 degrees, the pests begin their departure from wintering. They overwinter in forests and gardens under fallen leaves. At the same time, the wintering place may be located at a distance of up to 200 km from the planted fields. The bug bug vector of the bug is highly dependent on the wind direction.

The period of egg laying in insects begins one or two weeks later, after the flight to the field. Eggs are laid on shoots of cereal crops, weeds and dried plants. During the season, the female can lay up to 15 clutches containing 14 eggs each.

The development of bugs of turtles lasts about 35 days, and the total duration of their life is on average 10-11 months. It is noteworthy that the insect bug insects eat the same way, regardless of their age, so one flock of such pests can destroy more than one planted area during the season.

Harm turtles

The first mentions of the pest date back to the end of the 19th century, but it received wide world fame only in the second half of the last century.

Today, the turtle is the main threat to growing wheat on any scale.

The bedbug easily damages both small crops of garden plots and significant harvests of production areas, regardless of the age of the individuals in the flock.

At the moment there are a lot of photos with the bug of a harmful bug, so every farmer easily recognizes him by his appearance.

The area of ​​insect damage are fields and vegetable gardens planted with grain crops and wild cereals. It often attacks maize, oats and barley, but the bug causes especially great harm to the wheat.

When an insect is bitten by a stalk, saliva enters the wheat spike, which contains an enzyme harmful to the plant.

As a result, immature grain, insufficient viscosity of wheat gluten, and, consequently, a decrease in the quality of the test.

On wheat, the bug bug is located differently, however, in most cases, the insect climbs into the inner part of the ear, as a result, the pest survives during harvesting and ends up with the crop in barns and granaries. At the same time, being near the mountain of grain, the characteristic noise emitted by a crawling bug is clearly audible.

The crop hit by the bug has three main features:

  • withering of young shoots on a certain zone of a sowing area,
  • distortion of the structure of the ear, its fading,
  • damaged grain fades and becomes softer.

The bug bug turtle has been known for more than one generation of landowners, so experienced agronomists regularly inspect spikes in different parts of the fields in search of pests and traces of their presence. They know that if they do not take timely measures, then by the time of full ripening, nothing can remain from the harvest.

It is also very important to inspect the cereals for the presence of laid eggs there. Their timely destruction will relieve future problems with adults.

In many cases, the affected grain may not outwardly differ from healthy, but it will become noticeable at the final stage of its application - in the process of baking a flour product. The dough becomes gray, becomes too viscous.

For a human, the bug a harmful bug does not pose any threat. The insect does not bite and does not cause skin irritation, so you can safely shake it off or take it in your hand.

Prevention of bedbugs

In order to avoid loss of productivity and increase in the population of parasites for the next year, the bug bug should begin to be controlled with the prevention of the appearance of the pest. In addition to information training, the following measures should be taken:

  • soil fertilization with minerals containing phosphorus and potassium,
  • timely harvesting of ripened grain, quick selection and grinding of rollers. The harvest that was left on the field risks being an infected insect,
  • regular destruction of weeds, on the leaves of which eggs can be laid,
  • stubbling,
  • pretreatment of grain, removal of debris and dirt, drying.

Experienced farmers planted cereals in areas surrounded by forest belts, plantings, etc. The dense layer of trees stands for the bug of the noxious turtle as an insurmountable obstacle that causes insects to look for another place of settlement. A large number of “bugs” bug bugs also inhabit the forests:

In some cases, when tillage for some reason is not possible or does not help, and spike damage is already underway, some landowners produce chickens on a small plot. One chicken can kill more than a hundred bugs in a day, but in this case the harvest itself may suffer.

Nowadays there are specially bred varieties of wheat that are resistant to attacks of parasites. The bug bug is much less eating Akmolinka, Krasnokutku, Mironovskaya 808, etc. The peculiarities of these varieties allow farmers to avoid a significant loss of yield, however, such sowing will be more expensive than usual.

Methods of dealing with bug bug

The mischief bug eats the cultures that are most valuable to humans in equally large volumes, regardless of the age of the individual, therefore measures to combat it must be cardinal.

At the beginning of the season, before proceeding to radical action, you should make sure that all preventive measures are taken to prevent the appearance of a harmful insect. If nothing has helped, and the mischief bug continues to develop along the site, you need to start using chemical agents.

Each of the drugs has its own characteristics, so before you start using, you should carefully read the description, which is usually located on the back of the container label.

Instructions and photos of these and similar drugs can be easily found on the websites of manufacturers or online stores.

Pest Control Technology

Bug harmful turtle begins its intensive development of the site during the formation of the spike. It was at this stage, while the damage to the cereal did not begin at full strength, spraying yields the maximum result.

Treatment with chemicals is carried out either by air (at large production sites) or manually. Spraying should be carried out in strict accordance with the instructions, otherwise, at best, the method of struggle is ineffective, at worst - the wheat grain damaged by chemicals becomes poisoned.

Most chemicals are sold in concentrated form and require self-dilution with water.

Before preparing the mixture and throughout its use, you must wear protective equipment, which includes rubber gloves, a protective suit, mask, or respirator. In case of contact with the skin or respiratory tract, the liquid and its vapors can cause an allergic reaction, irritation and chemical poisoning of varying degrees.

Before pouring the finished solution, the sprayer is best tested for operability with ordinary water, in order to repair it, if necessary, be carried out without the presence of toxic substances.

Disinsection is usually carried out in the morning or in the evening. At this time, the sun is less active, and the evaporation of harmful substances is much less. It is also important to follow the weather forecast, so that during the spraying or after it, it does not rain. Heavy rain can frighten away the bug and wash away poisons, and work will be in vain.

The bug bug can react differently to the effects of the chemical, however, in most cases, as a result of the gradual accumulation of poison in his body, there is a decrease in appetite and speed of movement of the pest. The substance damages the nervous system, causing paralysis and inevitable death.

Biological features of insects allow them to adapt over time to the effects of chemicals, so insecticides need to be alternated regularly.

The bug bug gets a dose of poison, not only in the process of eating the grass, but also during external contact with poisonous plants, therefore, in order to get rid of the pest once and for all, the treatment must cover the whole part of the spike, as well as weeds and plants adjacent to the site.

Conclusion

Having an idea of ​​the appearance and peculiarities of the insect's behavior, the bug of the harmful bug does not pose a particularly great threat to the agrarians. After sowing, the following rules should be followed:

  1. Fertilize soil with phosphorus and potassium.
  2. Inspect spikes regularly for insects or eggs. Inspect the damaged plant.
  3. If a bug is detected, start preparing for spraying.
  4. Carefully study the instructions of the substance.
  5. Wear chemical protective equipment and thoroughly spray the infected area and surrounding plants.
  6. Timely clean the grain and process it before placing it in the barn.

Performing these steps will allow you to get a full-fledged harvest this season, and, preventing the development of the pest, will facilitate the cultivation of wheat and other crops in subsequent years.

Fight against a bug

The harmful turtle is a member of the family Shchitniki-turtle, the most dangerous pest of agriculture. These insects severely damage crops and, in particular, wheat.

An adult insect has an oval body from 10 to 13 mm in length, gray, yellow-gray, brown-gray in color. It has a very dense shell, resembling a shield with patterns in the form of dots and lines of whitish, greenish or silver-whitish color.
