Abstract

The work presents the results of a study of the features of the seasonal development of a dangerous invasive insect the box tree moth, Cydalima perspectalis Walker, specialised on plants of the genus Buxus L. Models for forecasting the dates of the resumption of larvae activity in spring after the winter diapause, the first adult flights of the overwintered generation and the appearance of the first summer generation of larvae have been developed for the southern regions of Russia. The accuracy of the forecast of the larvae coming out of the winter diapause is 3-4 days, of the adult flights and the appearance of the first summer of larvae is 9-10 days. The developed models can be used as a tool to improve the control of this pest.
