“…In recent decades, the range of insecticides and the system of their use have been almost completely updated. It has been established that their repeated use leads to the complete destruction of both harmful arthropods and entomoacaryphages, disruption of trophic relationships that stabilize the garden agrocenosis, as well as a change in the dominant species composition of insects and mites (Balyikina & Yagodinskaya, 2019).…”

The most widespread culture in the structure of fruit plantations in Ukraine is the apple tree. An important factor in the highly efficient production of apples is ensuring proper phytosanitary state of plantations and observing agrotechnological methods of growing, which is possible only with constant and long-term monitoring of the species composition, population dynamics, biological and ecological features of the entomoplex. The aim of the study conducted in 2005-2020 was to determine the ecological structure of the harmful entomocomplex of apple orchards under the conditions of the Central Forest-Steppe of Ukraine. Field, laboratory and chamber research methods generally accepted in ecology and entomology were used to fulfill the tasks. In the study, 52 species of phytophagous insects from 25 families and 7 orders were identified; 5 species of phytophagous mites from 3 families of Tetranychidae (Panonychus ulmi Koch., Tetranychus urticae Koch., Scizotetranychus pruni Oudms.), Bryobiidae (Bryobia redikorzevi Reck., syn: Bryobia praetiosa Koch.), Eriophyoidae (Eriophyes mali Nal.) were also found. The taxonomic structure of phytophagous insects was dominated by representatives of the orders of Lepidoptera (24 species), Coleoptera (14 species) and Homoptera (9 species), the portion of which collectively amounted to 90%. A range of Lepidoptera represented by 13 families was characterized by wide species diversity: Tortricidae, Gracillariіdae, Yponomeutidae, Lyonetiidae, Cossidae, Sesiidae, Coleophoridae, Lasiocampidae, Geometridae, Pieridae, Arctiidae, Noctuidae, Orgyidae, which accounted for 46% of the harmful entomocomplex. The most numerous (dominant) species for the period 2005-2020 were three species of aphids (Aphis pomi De G, Dysaphis devecta Walk, Dysaphis mali Ferr.), apple moth (Carpocapsa pomonella L.) and leaf rollers (Archips rosana L.). In terms of trophic specialization, polyphages dominated 75% (39 species) of apple tree agrocenoses, 10% (5 species) of oligophagous insects, 15% (8 species) -monophages. The life forms were dominated by phytophiles -dendrobiotes, the percentage of which in the total structure of insect pests was about 90%. The species composition of harmful entomofauna and ecologically constant species of phytophagous insects in apple plantations in the Central Forest-Steppe of Ukraine were specified. A promising study is to clarify the features of the biology of the most harmful phytophagous insects under the conditions of climate change and to develop environmentally safe means of protecting apple plantations from pests.

The effectiveness of the biopreparation “Fitoverm, CE” in protecting a young apple orchard in 2021 (October) from green (Aphis pomi) and gray (red-gallic) apple aphid (Dysaphis devecta) was studied. The research was conducted in the educational garden of the Orel State Agrarian University in 2023–2024. The scheme of the experiment included two factors: A — varieties (Orel striped and Veteran), B — doses of an insecticide of biological origin “Fitoverm, CE” based on aversectin C (0.4, 0.6 and 0.8 l/ha). Treatment with the drug “Fitoverm, CE” was carried out in the first decade of May, accounting — on the 7th, 14th and 21st days. In the garden, the calculations were carried out visually. On 5 trees of each variety, 20 young shoots located on different sides were evaluated. In laboratory studies, a Levenhuk STX RC1 remote-controlled microscope was used, the country of manufacture is China for Levenhuk, Inc. (USA). The magnification is 200 times. The varietal specificity of the Orlovskoye striped and Veteran apple trees in relation to the population of Aphis pomi and Dysaphis devecta was revealed. The Oryol striped variety is more attractive as a food resource compared to the Veteran variety. A sufficiently high population of aphids (52.18%) of young shoots of the Orlovskoye striped apple variety in the control variant led to a decrease in the average length of branch growth by 58.1% compared with uninhabited ones. According to the Veteran variety, the population was lower (34.22%), so the growth of branches decreased to a lesser extent and amounted to 42.5%. A large number of entomophages were noted in the agrocenosis of the apple orchard, among which the imagos Psyllobora vigintiduopunctata and Coccinella septempunctata, their larvae and larvae of Cecidomyiida and Syrphidae prevailed. The best result in terms of “biological efficiency” was obtained at a maximum rate of consumption of a biological product of 0.8 l/ha and amounted to 85.6% for the Orlovskoye striped variety, 86.7% for the Veteran variety.
