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 – 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, not 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, far from the field and move to the wintering grounds during the period when the harvest of winter crops is completed until the end of October. The imago should accumulate the necessary fat reserves for the winter and if they are undernourished, and the crop is already harvested, they are fed in the litter on the field or along the road with seeds of wild trees and wild cereals. The spring cycle repeats.
The population of the harmful turtle is found in steppe forest belts of Russia (Lower Volga region, Stavropol and Krasnodar Krai, Rostov Oblast and other regions), Ukraine, European countries, in some countries of Asia and North Africa.
What hurts a bug bug
A harmful bug at an early stage of development in the state of the larva damages by biting at the base of a young shoot, a more adult individual – imago – can dig into the grain. A characteristic sign of a bite is a small, brown, loose point.
What harm does a bug make a harmful bug?
The bug bug 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 up, 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 poor 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.
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 state of the plant should 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 the 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, with whom it is more difficult 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. The calculation is carried out on m2, the processing should be carried out upon detection: 2 winter survivors; during flowering and to the milky state from 5 larvae of imago; with further growth – if 2 adults 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 of grain before sending it to storage in the barn.
How to get rid of the bug bug turtle quickly?
The most effective result in detecting overwintering imago is provided by a spraying method in two stages. The first is to fight 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, KE
- Volley, EC
- Imidor, VRK
- Karachar, KE
- Tagore, KE

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 long, 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.

Harmful bug bug
The bug bugs 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 happened to be in the apartment, you can simply throw it away.
Thanks to the device of the oral 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 into 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 there, 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 private 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 capable of producing juices in large quantities.

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 the 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;
- late 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 decline 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 when it is fed.
Insecticides against harmful turtles are presented in a wide range:
- 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 is against bugs that survived the winter, the second 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 select the required 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 an insect disease called “white muscardine”.
A mushroom, getting into the body of an 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 a harmful bug were very effective (Suzdal
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 respecting the processing time.
Bowerin, of course, is difficult to get, but it works well. For humans, it is non-toxic and safe. No need to use hazardous chemicals against the bug

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. For example, the green bug prefers to eat exclusively
Bug harmful bug (Eurygaster integriceps)
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 spikes 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, the photo of which 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 perfectly 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 wheat stalks, 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
Bug turtle is a big 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 the 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 a 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.

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.
The photo shows bug on the spike:
How do bugs and turtles hurt 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 a 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, the chipping of the grain, the change in its color or the traces (points) of the bug bite are noticeable.
Scientists have found that the bugs are harmful turtle prefers to eat the most valuable for the human varieties 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 bugs parasitized bugs, 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 plant with its long proboscis, the bug introduces an enzymatic liquid into the capillary, which then spreads along the upper part of the stem and the spike.
The most interesting thing is that flour ground from grains of damaged ears looks the same as 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.
Measures to deal with the bug
In order to prevent contamination of grain by harmful bugs, you need to follow some rules:
- Timely harvesting of mature crops, direct method of combining;
- Timely fight against wild weeds, but at the same time compulsory preservation of forest belts and areas of wild vegetation near the field in which natural enemies of bedbugs breed;
- Fertilizer fields. Especially effective will be the use of potassium and phosphorus;
- The use of varieties with increased resistance against parasites.
It is also useful to read: The appearance and characteristics of the life of the Italian bug
However, if the bug bug bug has already penetrated the field and began to multiply there, you need to take drastic measures. In this case, help chemicals adapted specifically for such pests.
It is best to carry out the treatment at the time when the ear has only reached the milky ripeness. At this time, the parasites are just beginning to colonize it, and the resistance will be most effective. You can, for example, use the following drugs:
- Aktara. Insecticide group neonicotinoid, effective when spraying. An hour after application, the insects stop feeding and die completely within 24 hours. Aktara is especially effective at a large accumulation of insects, allows you to quickly and easily destroy the main part of the population;
- Karate Zeon. A pyrethroid insecticide that infects the insects’ nervous system and causes their early death (from several hours to days). The drug is available in suspension, prevents the emergence of resistance in pests.
And some others.
Spraying a solution of drugs can be carried out from the air, or be sent locally directly to the plants. Both of the above insecticides have a fairly wide spectrum of activity, and in addition to the harmful bug, they also destroy other pests of grain crops.
In our farm, a harmful bug is usually poisoned with Aktar. The tool is good, bugs only have time to fly, as we spray the composition and after a couple of days they are gone. When the larvae hatch, spray again. After that, no problems, not only with the bug, but also with other parasites. This is one of the best insecticides, for a long time only we use it.
Alexander Semenovich, Pavlograd
Bug harmful turtle annually causes huge losses to agriculture, being one of the main pests of grain crops. That is why preventive measures to combat it should always be taken, and at the beginning of the infection – to act quickly and massively.

Bug harmful turtle
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 cereals, and if effective measures to protect the crop are not taken in time, the economic damage will be noticeable.
Features of the species, habitat
Bug harmful turtle belongs to the family of shushnikov-turtles. This type of name was given 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 come out of the wintering area 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, the embryo develops within a week, after which a larva hatches into the light. 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.
No matter what the bug bug eats, whether it is corn or wheat, but its mouth apparatus does not allow to eat solid food. In the early stages of development, the larvae make punctures in the stems of the 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, pests are frequent guests in homestead plots and summer houses, where the bugs are harmful turtle damages the crops of corn 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. The bugs are 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 do not carry any threat. But taking the shield with bare hands is not recommended, as it secretes a special strong-smelling enzyme to scare the birds of prey.
Shield bug-turtles harm agricultural plants. Their favorite food is barley, corn, 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 gardening and household plots.
The bug bug bugs feed on plant sap, for this it pierces the stem or spike and ferments the contents internally, and then sucks it out. Eroded 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 ears and shoots;
- the presence on the mature grains of microscopic chips and points in 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 capable of destroying crops on vast areas.
Fighting bug bug
There are two main ways to deal with parasitic bugs harmful turtle:
- Chemical, when insects are eliminated with the help of potent insecticides.
- 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-bug are:
- Bassoon – intestinal insecticide from the group of synthetic pyrethroids causes a massive death of adults and larvae, which heals 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, leading to infection and death. This method is environmentally friendly. Effective method of distribution in the habitat of the tortoiseshell-turtles 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 an integrated 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 destroying insects, but also at creating unfavorable conditions for their development.
Bedbug – a harmful turtle: species and control measures
A small oval-shaped bug bug is considered one of the most dangerous pests of agriculture. Parasitizing on crops, large colonies of these insects can significantly reduce the quantity and quality of the crop.
Well-kept 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.

How to recognize the enemy in person?
In 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 are often harmed by the green bug (stinker), beetroot and the bug bug.
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. For gardeners, this parasite is completely harmless, as it damages only cereals.
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 the grain with the proboscis, 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 the flour ground from the damaged bedbugs grain 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 process of the formation of protein – grain gluten. The dough from low-gluten flour does not rise well, is gray in color and is unsuitable for baking bread and making pasta.
Stink bugs, or green bug, often found on tomatoes, eggplants, 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 sprigs 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 strong odor, 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 umbellate (carrots, dill, cilantro). Piercing the leaf trunk with the proboscis, the insect feeds on the juice, and the plant fades.
Due to the fact that shields and beetroot bugs sometimes attack only sprouts or cabbage seedlings that have emerged from the soil, the damage caused by them can be very significant.
For mature adult roots 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, which harm garden and garden plants, the measures to combat them are almost the same:
- hand collecting insects;
- the use of toxic chemicals for destruction;
If there are small children in the family who can pick and eat berries or other fruits in the garden themselves, 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 look like 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 hours. The drug is easily washed off by rain, therefore, after precipitation, the treatment must be repeated.
Karate insecticide 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 proven agent – Karbofos. Its disadvantage is a strong smell and high toxicity. The drug is best treated plants at a young age, before the fruit set. 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.
In order 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.
Bug harmful turtle: methods of struggle
From the moment of cultivation, man constantly encountered 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 bug turtle, 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 countries.
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 strongly 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 insects of the pest bug eat the same way, regardless of their age, so one flock of such pests can kill more than one planted area in a season.
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 freely 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. Corn, oats and barley often attack, but the bug causes especially great harm to the wheat.
When an insect is bitten by a stalk, saliva enters the ears of wheat, 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 dough.
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 of which the pest survives during harvesting and ends up with the crop in the barns and granary. 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:
- wilting of young shoots in a certain zone of the sown area;
- distortion of the structure of the ear, its fading;
- damaged grain fades and becomes softer.
The bug bug is already known to more than one generation of landowners, so experienced agronomists regularly inspect spikes in different parts of the field 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 by preventing the occurrence of a 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. Harvest that is left on the field risks being an infected insect;
- regular destruction of weeds, on the leaves of which eggs can be laid;
- pretreatment of grain, removal of debris and dirt, drying.
Experienced farmers planted cereals in areas surrounded by forest belts, plantings and
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 in a small area. 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. Bug harmful turtle eats much less Akmolinka, Krasnokutku, Mironovskaya 808 and
Methods of dealing with bug bug
The bugs are a harmful turtle eating the most valuable human culture in equally large volumes, regardless of the age of the individual, therefore, measures to combat it should be cardinal.
At the beginning of the season, before proceeding to radical actions, 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 manufacturers’ websites 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, until the damage to the cereal began in full force, the spraying gives 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 control method 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 the event 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, so that repairs can be carried out, if necessary, 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 the work will be in vain.
The bugs are harmful turtle 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 should cover the whole part of the spike, as well as weeds and plants adjacent to the site.
Having an idea of the appearance and peculiarities of the behavior of the insect, the bug of the harmful bug does not pose a particularly great threat to the farmers. After sowing, the following rules should be followed:
- Fertilize soil with phosphorus and potassium.
- Inspect spikes regularly for insects or eggs. Inspect the damaged plant.
- If a bug is detected, start preparing for spraying.
- Carefully study the instructions of the substance.
- Wear chemical protective equipment and thoroughly spray the infected area and the surrounding plants.
- Timely clean the grain and process it before placing it in the barn.
Following these steps will allow you to get a full-fledged harvest this season, and, not allowing the development of the pest, will facilitate the cultivation of wheat and other crops in the coming years.
