Specific composition of raspberry herbivorous pest in the Сentral Forest Steppe of Ukraine
Abstract
Goal. To study the species composition of herbivorous pests and to determine the dominant species on raspberry.
Methods. The research was conducted in the Forest Steppe of Ukraine during 2023—2024 years. Clarification of the species composition of herbivorous pests was carried out according to generally accepted methods. Insects were identified using markers. To study the species composition of raspberry herbivorous pests research methods generally accepted in entomology were used: mowing with an entomological net, visual inspection of plants, soil samples.
Results. The insects that were discovered during the research belong to 5 orders (Coleoptera, Hemiptera, Diptera, Hymenoptera and Lepidoptera). Oder Coleoptera, which included 6 species from 4 families, was characterized by the greatest species diversity. The analysis of the species composition of raspberry herbivorous pests based on feeding relationships showed that this culture is dominated by polyphages — 9 species, but the main damage is caused by 2 types of oligophages.
Conclusions. According to the results of the monitoring of the entomocomplex of raspberry in the Central Forest Steppe of Ukraine, 14 species of pests from 5 oders were found. Analysis of their species composition shows that representatives of the order Coleoptera dominated — 43%. It has been established that the most dangerous pests that cause significant damage in the Forest Steppe are a complex of pests of generative organs: the raspberry beetle (Byturus tomentosus F.) and the raspberry strawberry weevil (Anthonomus rubi Hrbs.).
