Description
For the research period (2003-2016), 57 pest species and 46 pathogens were recorded on stone and pomaceous fruits in humid Russian subtropics, among which the representatives of the order Lepidoptera and the division Ascomycota predominate. The greatest number of the species was recorded on the apple tree - 35 pests and 25 pathogens, the smallest - on cherry and sweet cherry trees (13 and 10, respectively). 43,7 per cent of the species are polyphages, while the relative abundance of monophages among fungi is higher than among arthropods. The species with activity in the summer are prevalent. A group of species that are harmful in humid subtropical environments all year round (11 species of phytophages and 19 pathogens) was identified. Analyzing the changes in the species composition of the complex through the time, we can speak about the relative stability of the dominant species. The group of the typical dominant species of pests for almost a century has included Grapholita molesta Busck., G. funebrana Tr., Cydia pomonella L., Taphrina deformans (Berk.) Tul., Stigmina carpophila (Lév.) M.B. Ellis, Monilinia laxa (Aderh. et Ruhland) Honey, M. fructigena Honey, Podosphaera leucotricha (Ellis & Everh.) E.S. Salmon, Venturia carpophila E.E. Fisher and pear V. pyrina Aderh. Eriosoma lanigerum Hausm., Scolytus mali Bechst. and Tranzschelia prunispinosae (Pers.) Dietel are currently dropped out from the group of the dominants; Halyomorpha halys Stål, which is a new pest for Russia, was added. Groups of the species with sharp fluctuations in abundance or frequently encountered were distinguished
