Effectiveness of bioinsecticides against the caterpillars of <i>Cydalima perspectalis </i>(Walker, 1859) on the Southern Coast of the Crimea

Boxwood moth Cydalima perspectalis (Walker, 1859) is a serious threat to plants of the genus Buxus in all agroclimatic regions of the Crimea. The use of bioinsecticides is one of the environmentally safe and effective methods of reducing the number of phytophages. The use of preparations of Lepidocidae Bitoxibacillin in three standards of application provided high biological effectiveness against boxwood moths caterpillars of all ages. For older caterpillars on the fifth day, the biological effectiveness of Lepidocidae Bitoxibacillin in all standards of use was 100%. Fitoverm proved to be more effective against young and middle-aged caterpillars. On the fifth day after treatment with Fitoverm, biological efficiency for young caterpillars was 98,8%, and for middle-aged caterpillars - from 94,4 to 96,8%.
