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
