Bark beetle - ways to control pest

Gardener amateurs, protecting their crops, are obliged to know the pests of cultivated plants to prevent the damage they cause. Insects that settle under the bark of plants are the biggest problem for gardeners. One of the common pests is a bark beetle, which, in turn, has several varieties, "specializing" on different plants.

Description of pests

Bark beetles under the bark of trees turn the courses, as a result of which branches die and trees die. The wrinkled stalker prefers stone fruit (for example, cherry), but can damage the bark of mountain ash, irgi, dogwood. The insect itself is about three millimeters, with a black head and brown lining. The beetle is called a bark beetle, because its larvae from the uterine process are able to make up to thirty courses under the bark of the plants. From their activities damage the trunks of young trees and branches in adult plants.

Fruit sapwood is a bark beetle, which likes to settle on apple trees, but can also live on other fruit trees. Of the larvae, who have waited for the winter under the bark, pupae are obtained, and bugs are derived from them. Insects black with a shine of color have a size of about four millimeters. Years of bark beetles begin with the flowering of trees and can last until mid-summer. The larvae of this type of beetle make six centimeters long and two millimeters wide in the bark of the plant.

Western unpaired beetle bark beetle damages deciduous trees of various species. Unlike saplings, who settle on sick and weakened trees, this insect chooses healthy plants. The explanation lies in the way the beetle feeds. Its larvae do not make moves, they feed on the mycelium of the fungus, which appears in those places where the female, gnawing through the courses, excretes the juice. First of all, those trees that were overfed with nitrogen suffer and are damaged.

Methods of pest control

It is important not only to represent the characteristics of pest life cycles, but also to know how much struggle with bark beetle can be effective, which methods are best suited. It is necessary to regularly inspect plants, tree stems and their skeletal branches. When pests are detected, measures need to be taken. One of the ways - catching beetles after the spring pruning of plants. Cropped branches should be placed around fruit trees with an emphasis on their skeletal branches. Beetles will settle on sticks. In autumn it is best to burn a stick.

Most often to combat the bark beetle, it is recommended to prune the damaged branches, trim the tree trunks with a mixture of manure and clay (you can use oil paint, though it is not so effective). Since the outbreak of pests occurs after flowering of trees, they are advised to spray it during this period. Moreover, bark beetle, the fight against which is such a big problem, is exterminated by the same chemical preparations that are used from leaf-eating pests. For example, such as "Arrivo", "Vectra" and others. It is better to repeat the treatment of plants after two weeks. To destroy the larvae of the bark beetle, one can dial a chemical preparation into a disposable syringe and inject it into the insects pierced with insects. Carrying out the processing of trees from aphids, scabs, leafworms, it is necessary to moisten abundantly the trunks and bark of plant branches. Treatment with insecticides leads to a reduction in the percentage of plant damage caused by bark beetles, and they stop multiplying in large numbers.

In addition to pruning the damaged branches, it is necessary to clean the areas of the bark that the bark beetle has gnawed, removing mosses and lichens. Bark beetle on the damage he does to horticulture, compared quite often with the Colorado beetle. The bark beetle is voracious, and destroying it is quite difficult. And yet, there are methods of struggle. Some of them are described in the article. The most cardinal way is to cut down the infected plant.
