Slug of the deer

-

Evetria turionana - butterfly species.

Appearance: butterfly with wingspan of 10-20mm, color from yolk brown to rusty, with silver-gray, transverse bands.

Occurrence: It is a common pest of 6-12 year old and older pine trees and pineapples.

Biology: Butterflies fly in May and June. The female lay eggs singly on the top or side buds in circles on young pine trees. The caterpillars hatch from the end of June to the beginning of July, bite into the top buds and dump them. As a result, donuts die and peak functions take over from one side bud, but they can also be populated and destroyed by caterpillars. The call is made in April and May inside a delicate yarn of a hollowed donut. This is also where the pupa overhangs, which is characteristic of a residual spruce.

Economic importance: Feeding effects are visible in spring when buds are sprouting on the donuts and the buds themselves are undeveloped and soft in the root part. Crawler caterpillars cause shoot damage, underdevelopment or tip bud diarrhea, endothelial capillary termination, and crown deformation.

Economic recommendations: There is a mechanical struggle involving the cutting or breaking down of mowed shoots that feed on caterpillars. These shoots stand out of the undeveloped bud topped into a gray color. Bibliography
