The information on the dynamics and harmfulness of leaf-biting Lepidoptera (looper and leaf-roller) populations in apple tree gardens of different constructions is given. The evalualion of weather conditions influence on their harmfulness under diffrent relations by species is presented. The regression equations allowing to calculate complete thresholds of harmfulness for leaf-biting Lepidoptera depending on their number, species composition and weather conditions during feeding are described
