Species composition of phytophages on ornamental plants

Abstract

Goal. Monitoring the phytosanitary status and determining the species composition of phytophages on decorative coniferous and deciduous plants. Methods. Field — determination of the species composition of pests and the dynamics of the number of main species; laboratory — determination of pests selected on experimental plots. Research was conducted in accordance with generally accepted methods in entomology and plant protection. Results. In the industrial plant nursery of open soil «Megaplant» located in the Kyiv region, Fastiv district, village The monitoring of the phytosanitary state of ornamental plant plantations was carried out in Trilys. The natural saturation of harmful organisms and the level of their harmfulness were studied. Conclusions. It has been established that plants in industrial nurseries in open ground are damaged by a large number of insects and mites. The most dangerous and widespread on conifer ornamental plants were 8 pests from the following families coccids (Coccidae), bark beetles (Scolytidae), adelgids (Adelgidae), snout beetles (Curculionidae) and spider mites (Tetranychidae); 9 most harmful species from the following families were noted on decorative leafy plants: crambid Snout Moths (Crambidae), mealybugs (Pseudococcidae) and аrmored scales or diaspidids (Diaspididae), eriophyidae mites (Eriophyidae), aphids (Aphididae), snout beetles (Curculionidae), scarab beetles (Scarabaeidae).
