Abstract

The article provides monitoring of the population of bark beetles (Scolytinae) and their entomophages in the forests of the Zaili Alatau on the territory of the Ile-Alatau state national natural Park. As a result of monitoring of bark beetles (Scolytinae), the species composition of bark beetles and their entomophages was established on the endemic schrenka spruce in the Zaili Alatau. One of the possible centers of outbreaks of mass reproduction of bark beetles is shrinking Shrenka spruce trees found in a number of gorges. In this regard, we carried out a monitoring of the populations of bark beetles (Scolytinae) in the endemic spruce spruce in The Zaili Alatau. In the years of the study, there were 17 species from the family of bark beetles (Scolytidae), and the gauser bark beetle (Ips hauseri Reitt) dominated the registered species of bark beetles (Solytinae). Also found is a predator from the order of Hemiptera (Hemiptera) bugs crumb-Scoloposcelis pulchella Zetterstedt which has not been previously recorded in Kazakhstan.
