Gardeners-lovers, protecting their crop, are obliged to know the pests of cultivated plants to prevent them damage. Insects that settle under the crust of plants are the biggest problem for gardeners. One of the common pests is a cored beetle, which, in turn, has several varieties, "specializing" on different plants.
Insect pest description
Coroes under the crust of trees are taking the moves, resulting in dying branches and trees die. The wrinkled sorridge prefers bone cultures (for example, cherry), but can damage the Corra Ryabina, Irgi, Kizyl. The insect itself is about three millimeters, with black head and brown flaws. The beetle is called a korochet, because its larvae from the uterine move is able to do under the crust of plants to thirty moves. From their activities, the trunks of young trees and branches in adult plants are damaged.
The fruit crook is a coroede's beetle who loves to settle on the apple trees, but can also live on other fruit trees. From the larvae who flocked the winter under the crust, the dolls are obtained, and beetles are derived from them. Insects black with color glitter have a size of about four millimeters. For years, koroedov begins with the flowering of trees and can last until the middle of the summer. The larvae of this type of beetle is done in the plant's crust of the plants with a length of six centimeters and two millimeter width.
Western unpaid bug cored damages deciduous trees of various breeds. Unlike salaries who settle on patients and weakened trees, this insect chooses healthy plants. The explanation lies in the way the beetle. His larvae do not move, they feed on mycelium of the mushroom, which appears in those places where the female, breaking through the moves, allocates juice. First of all, they suffer and damage those trees that were reconciled by nitrogen.
Ways to fight pests
It is important not only to represent the features of the life cycles of pests, but also to know how much the fight against the core can be effective, which methods are best suited. It is necessary to regularly examine plants, trees strains and their skeletal branches. When pests are found, measures must be taken. One of the sprues - caustic cavities after the spring pruning of plants. Cropped branches need to be placed around fruit trees with a focus on their skeletal branches. Beetles will settle on sticks. In the fall, the sticks are best burning.
Most often, it is recommended to deal with damaged branches, the coating of tree trunks with a mixture of manure and clay (can be used with oil paint, however, it is not so effective). Since the departure of pests occurs after the flowering of trees, they are advised to spray in this period. Moreover, the croroede, the struggle with which represents such a large problem, is exterminated by the same chemical preparations that are used from leaf-making pests. For example, such as "Arrivo", "Vectra" and others. Plant treatment is better to repeat two weeks later. To destroy the larvae of the Koroeda, it is possible to type in a one-time syringe. Conducting trees from Tsley, shield, leaflerting, it is necessary to abundantly wasting trunks and bark of plants branches. Processing insecticide leads to the fact that the percentage of damage to the plants with cores is reduced, and they cease to multiply in large quantities.
In addition to pruning damaged branches, cleaning of the cortex can be cleaned, which is sprinkled by the beetle, removal of moss and lichen. Coroeda in the damn, which he inflicts gardening, is compared quite often with the Colorado Bucket. Coroede is voracious, and it is quite difficult to destroy it. Nevertheless, there are methods of struggle. Some of them are described in the article. The most cardinal way is to cut down the infected plant. A more sparing option is a clipping of affected branches and burning them. Using the above-listed struggle options, gardeners can protect their garden from a dangerous pest.
