A note that wreckers of gardens – shchitovka represent.
Dangerous wreckers
On young branches of an apple-tree and a quince it is possible to see small cambers in the form of small pillows and the extended hyphens. What can it be?
On a bark of a trunk and branches motionlessly sitting small insects covered with dense wax-like guards sometimes meet. These are shchitovka and lozhnoshchitovka. At first sight they are even not similar to insects, remind outgrowths on a bark rather. Possessing ability quickly to breed, shchitovka often entirely pokryvayut a bark of branches and trunks of trees and bushes.
Most likely, on your trees lodged a yablonny zapyatovidny shchitovka (guards are bent in the form of a comma) and Californian (in the form of small pillows). Eggs milky-white, winter under guards died off samok on a bark of trunks and branches. Vesyona, soon after flowering yabloni, from eggs otrozhdayutsya pale yellow larvae, they prisasyvayutsya to a bark also become covered shhitkami. Development of larvae prodolzhaetsya 40-50 days, then they prevrashhayutsya in females who otkladyvayut on 50-100 eggs also perish.
Wreckers develop in one generation. Clear trees of the old died-off bark. It is better to do all this in the autumn or in the early spring while eggs didn’t leave and larvae vagabonds didn’t disperse. In the summer of vagabonds mozhyono to eradicate, using the same preparations, which primenyayut in fight against other wreckers of a garden: Varand, Detsis, Detsis Profi, Konfidor, Konfidor Maxi, Calypso, Zeus.
