DOMINANT PHYLLOPHAGES OF ULMUS PUMILA PLANTS OF THE GREEN ZONE OF NUR-SULTAN CITY

Abstract

Artificial plantations of the green zone of the city of Nur-Sultan are of great ecological importance for improving the state of the environment and creating attractive recreational areas for residents of the capital of Kazakhstan. In connection with the periodic occurrence of outbreaks of mass reproduction of various types of phyllophagous insects in the green zone, it became necessary to clarify their species composition and assess the danger to plantings. This article presents the results of the analysis of data on the dominant species of leaf-eating insects Ulmus pumila. The studies were carried out according to the methods generally accepted in forest pathology and entomology. Dangerous species that give strong outbreaks of mass reproduction and can lead to a strong weakening of plantations are Erannis defoliaria, Lycia hirtaria. Species that have not seen outbreaks for a long time but pose a serious threat to plantations are Exaereta ulmi and Arge captiva. Orchestes steppensis is a mass species, damage to which does not have a decisive impact on plantations, but leads to weakening and loss of aesthetic qualities.
