PHENOLOGY OF A LEAFROLLER COMPLEX IN APPLE ORCHARD OF FOREST STEPPE OF UKRAINE

Abstract

Studies were carried out in the years 2012–2013 in apple orchards of Tarasivskii agricultural enterprise, Kiev region, Ukraine. The purpose of the current study was to determine and monitor the structure of the leaf rollers complex using pheromone traps, finding out the relation between the occurrence of moths, the sum of effective temperatures and rainfall amount. This study has shown that changes in meteorological parameters affect the ecology of leafroller complex resulting in an increase of generation number, duration of imago flight and restructuring of a leafroller complex.
