Features of phenology of apple moth in conditions of warming of climate in Forest-Steppe

Abstract

Purpose. To investigate the changes in the phenology of apple seedlings in the Ukrainian forest-steppe gardens. Methods. Commonly accepted methods of faunal studies in entomology, population ecology, plant protection. Results According to the results of the experiment, the beginning of the fly of the butterflies of the apple seedlings of the overwhelming generation on the pheromone traps in 2013 was recorded in the first decade of May (CET 80.4 ° C). The peak of the fly fell on 25.05.13 at SEET302 ° C, trapping traps made 40 traps per 5 days. The peak of the first year's flight fell on July 15, 13, 2002 (CET 872.5 ° C), the trap catches were 23 pieces / trap in 5 days. Also noted is another peak of the fly, which indicates the development of butterflies 2 nd generation from 10.08.13 (SET 1156 ° C) to August 30, 13th. The third peak of the fly in terms of the number of butterflies significantly exceeded the first two peaks. This is due to the use of pesticides during the vegetation of the garden and their absence before harvesting. Conclusions During the flying of the apple tree marmot on the pheromone traps there is an overlay of development phases, which makes it impossible to determine the limits in the cycle of phytophagus development. For monitoring of the number of preimaginal stages of apple tree planting, fishing belts are used.
