BIOECOLOGICAL FEATURES OF BUTTERFLIES PESTS THAT DAMAGE CONIFEROUS TREES

Abstract

Annotation. In the course of scientific research in the period 2021-2023 on biology, ecology, and biodiversity of pest butterflies in Southeastern Kazakhstan, the following data were obtained. Among the most common and harmful insects that damage buds and shoots on various types of spruce and artificial pine plantings, we have registered 5 species from the family of leafhoppers – Tortricidae: wintering – Evetria (Retinia) bioliana Schill., summer - E. dulpana Hb., kidney – E. turionana Hb., tar - E. resinana Hb.(resinella L.) and the middle kidney bean – E. turionana Hb. Shoots: wintering, summer, kidney, middle kidney develop in one generation. The biological characteristics of the following species are given: Evetria buoliana Schif. - Wintering snowbird, Evetria dulpana Hb. - Pobegovyun summer, Evetri turionana Hb. - Kidney bean, Evetri resinana Hb.(resinella L.) - Resin bean, Evetria turionana Hb. - Middle bud seedling, Cacoecia piceana L. - Pine needle leaflet, Diorictria abietella Schiff. - Pinecone firefly, Phalera bucephala L.- Silvery hole, Leucodonta bicoloria Den. Et Schiff. - Tufted bicolor, Biston hirtaria Sciff. – Brown-striped silkworm moth, Endromis versicolora L. - Birch silkworm, Suproctis (Euproctis) chrysorlhoea I. – Goldentail. Also, division experiments were conducted to test preparations of bitoxibacillin 60.6-76.7% against caterpillars of younger ages of cabbage scoops showed the high effectiveness of this drug.
