Abstract

During researches was determined the species composition of birch pests, which included representatives from groups of Hymenoptera (2 species), Hemiptera (4 species), Coleoptera (3 species) and Lepidoptera (2 species). The injuries were inflicted to the leaves, the earrings and the root system of the birch, and the underground authorities had the least overhead and the greatest degree of damage. The investigation of the plantations of the green belt of Astana have concluded that one of the factors that worsen the condition and stability of the silver birch are birch sawflies-miners. Conducted chemical treatmentsare ineffective against theseleaf-mining sawflies, therefore, further study of these species and determine the most effective way of dealing with them.
