Adaptation possibilities and changes in the bioecology of <i>Cydia pomonella L.</i> in the central region of the non-black soil zone of russia on the background of global warming

Relevance . Climate change has a significant impact on the bioecology of codling moth Cydia pomonella (Linnaeus, 1758) (Lepidoptera: Tortricidae) in Central region Nonchernozem zone Russia. Methods During research, both original and conventional methods were used. Pheromone traps, to study flight dynamics C. , installed orchards before apple blossom. Before emergence first butterflies at end summer, traps inspected daily, rest time 1–2 times week. Dispensers changed 1 5 weeks, adhesive inserts as they become dirty. Caterpillars leaving for cocooning caught trapping belts — corrugated cardboard one (inner) side 20 cm wide. Results The timing departure overwintered generation varies greatly by year dates (from 14.05 31.05), phenophases tree development «rosebud beginning flowering» «the flowering»), sum effective temperatures (SET) 40.0 122.6 ºС). In Moscow region, from April October, accumulation SET above 10 ºC is noted level 1009.2–1229.3 ºC, which, along with adaptive capabilities northern pest populations, ensures annual second ratio number generations depends weather conditions specific periods vegetation, however, exceeds economic threshold harmfulness (EPV) several every year. photoperiod this does not play decisive role influencing summer generation.
