The studies were carried out at the Federal State Budgetary Scientific Organization “Federal Horticultural Center for Breeding, Agrotechnology and Nursery” (FSBSI FRCHBAN) in 1995-2020. The aim of the research was to clarify the species composition, bioecology, and the characteristics of harmfulness of the main phytophages of apple trees in the Central Region of the Non-Black Earth Zone of Russia under climate change conditions. Route surveys were carried out in 5 regions of this zone - Bryansk, Kaluga, Moscow, Ryazan, Tula. When studying the bioecological features of the development and dynamics of summer of the codling moth and corrosive arboretum, along with other methods, pheromone traps were used. Trapping belts (sticky and corrugated paper) were used to signal the exit of the apple blossom beetle from wintering places, as well as the method of shaking off in the morning, at a temperature of no higher than 10˚С. The count of four-legged microscopic mites in the early spring period was carried out before the leaves blooming by the method of selecting the tops of annual growths up to 10 cm long, at 10 counting sites (to view the opening buds). During the growing season, 10 leaves were sampled (4 ... 5th leaves from the top of the shoot), at each registration area. The analysis of microscopic objects on the selected samples was carried out using an MBS-10 stereoscopic microscope. In the research area, new dangerous invasive apple phytophages were identified: corrosive arboreal tree Zeuzera pyrina L. (Lepidoptera: Cossidae), apple rusty mite Aculus schlechtendali Nalepa (Acariformes: Eriophyidae), apple felt mite Phyllocmespates malinus (Acariformes: Eriophyidae). The bioecology and harmfulness of autochthonous phytophages have changed significantly. The apple moth Cydia pomonella L. (Lepidoptera: Tortricidae) gives up to two generations, and the summer lasts up to 132 days. Red (Panonychus ulmi Koch. (Acariformes: Tetranychidae)) and brown (Bryobia redikorzevi Reck (Acariformes: Bryobiidae)) fruit mites, depending on weather conditions, develop in 4 ... 5 generations a year, common spider mite (Tetranychus urticae Koch. (Acariformes: Tetranychidae)) at 7. The prevalence of ticks reaches 100%, and the degree of damage to plants by them is up to 3-4 points. Damage to apple flowers by the weevil Anthonomus pomorum L. (Coleoptera: Curculionidae) reaches 60 ... 85%, the colonization of leaves and shoots by the red-gall aphid Dysaphis devecta Walk. (Homoptera: Aphididae) 35 ... 45%, fruit loss from apple sawfly Haplocampa testudinea Klug. (Hymenoptera: Tenthredinidae) 15%
