In each garden, in the country or in the garden, more precisely onany country site, you can find a huge number of insects, which is not surprising: it is their habitat. Some species are not dangerous for people and plants, others can cause significant damage to plantations. One of these insects is the green bug.
Pest features
Officially, insects of this species are called foresttree shields. The people called the insect bug-stink. This name is due to the strong smell that remains wherever the bug has crawled. And the smell remains for a long time. Tree shields are not eaten by berries, but their smell makes it impossible to use the crop: if the green bug on a raspberry settles, the aroma and taste of the fruit will be completely spoiled.
The trunk of an adult woody moth is oval andwide, and the head is small, with long antennae and proboscis. Dense shell, which consists of individual scales, reliably protects the insect. The color of the bug changes depending on the season: in early spring it is light green, as the young leaves on the trees, closer to the autumn it becomes dark green, and when the leaves begin to turn yellow, its color changes to brownish yellow. Thus, the color serves as protection from predators.
Reproduction
За сезон щитники дважды откладывают яйца.They choose the inner side of the sheets to place their offspring. After two weeks, the larvae come out of the eggs and immediately begin to feed. Food for young individuals is the juice of the leaves. To extract it, the larva pierces the leaf with a sharp proboscis, sucks the juice with it, instead of which it lets in poison. Once inside the leaf, the poison leads to its fading. After that, the affected parts of the leaves dry up, break off and fall off. If there are a lot of such leaves on a plant, it dries up - this is what can happen if a green bug settles on the site. The photo above perfectly demonstrates the consequences of his activities.
Larvae of each stage of generation (5 in total)covered with hard shell. To move to the next stage, you need to get out of the shell, and it is quite difficult. Therefore, not all larvae can survive to adulthood. Even more larvae are killed by birds and predatory insects, which also significantly reduces their population. Thus, their number is rarely so large that it can cause the destruction of bushes and trees.
The situation is completely different in the fields where cereal crops grow: a green bug causes the cereals to no longer bear fruit and then die.
Habitat
Green bugs inhabit throughout Europe.He lives wherever trees and shrubs grow. Gardens, forest plantations, green lawns are the places where you can meet the pest. But even if he himself is not visible, the damaged leaves will tell that this insect lives here.
Raspberry bushes, currants, gooseberries are most often affected. If they are not nearby, then they serve him with food:
- succulent herbs;
- deciduous trees;
- any berry bushes;
- cereals.
Preventive measures
Для существенного уменьшения количества древесных Shchitniki often help even agrotechnical activities. To do this, just need to know the features of their wintering: the shields are hiding under the fallen leaves and remain there until the cold weather passes. As soon as the heat comes, starving insects with redoubled energy are taken to eat everything that is available and acceptable to them as food. But if in the fall, just before the frost, to remove the fallen leaves with other plant debris and burn it all, the number of shchitniki remaining in the area will be minimal. According to experienced gardeners, if you also dig up the soil, then next year there will hardly be at least one green garden bug on the plot. There are other ways to remove the shield.
Mechanical removal
In other words, you need to collect insects with your hands.This is the most harmless way, but it is ineffective: it is difficult to see an insect in the green foliage of the same color. Moreover, it is very little chance of finding an egg-laying, so the number of shushniki is unlikely to decrease in the area with this method of dealing with them. In addition, it is necessary to constantly collect wood shields, since new insects will be born, and if they are not removed, the number of pests will increase.
The use of folk remedies
Преимуществом этого способа устранения древесного Shchitniki is complete safety for all living things, ranging from people and ending with plants. Important for many and low cost. The disadvantages include the low efficiency of home remedies, since the green bug does not die from them, but simply leaves the site for a while. To prevent insects from returning, it is necessary to repeat the treatment periodically.
To remove pests, you need:
- Dissolve dry mustard powder (10: 1) in cool water and immediately spray all plants.
- For 5 days, insist onion peel. To do this, take 10 liters of hot water 200 grams of husk. Mix and set aside. Treatment is carried out 3 times a day with a break of 5 days.
- Make a tincture of bitter wormwood and treat the infected plants if, for example, green bugs on currants are found.
- To scare away the pest, use the plant Klopogon (tsimitsifuga) - plant it in different places on the plot.
Other ways to fight
Как избавиться от зеленых клопов на растениях, if pests divorced a lot? Both methods described above in such cases can not have the expected effect, so you have to turn to the help of chemistry. Although to date there are still no insecticides designed to destroy tree shields, there are other tools that will help clean the area from pests. All of them differ in the mechanism of action and how insects enter the body:
- Contact. Used most often. Means penetrate into the body if the drug comes into contact with any part of the pest's body.
- Intestinal. Insecticides of this type begin to affect bugs only after they enter their digestive system.
- System. This type of drugs penetrates the plant tissue, after which the leaves of the eating shields are killed.
Experts advise to choose insecticides depending on the situation and begin to exterminate the woody scab only when its numbers really begin to pose a threat to the site.
Means for the destruction of wood shields
Because the stink bug was not listeddangerous insects, today there are no drugs intended to destroy this particular type of pest. The most popular organophosphorus drugs in this case are:
- "Fufanon".
- "Phosphamide".
- "Actellic".
- "Malathion".
The advantages of their use include highEfficiency - 1-2 treatments of affected plants are enough to clear the garden of woody shite. The disadvantage of this method is the high cost and toxicity of the drugs: they are dangerous both to people and animals, and they also poison the soil and produce. They destroy chemical agents and beneficial insects, therefore their use is not always justified. But this is not the main thing - after a few treatments the green bug does not react to the drug, since resistance occurs.
