Abstract
As a result of a study on the territory of the Sharyn SNNP in 2018-2019. 72 species of 13 families of aquatic hemiptera insects were identified. Among them, a large number of species stand out. Corixidae (27 species, 40%), Saldidae (10 species, 25%), Gerridae (9 species, 13%), in the remaining 8 families only 1-3 species are known. Salda sahlbergi Reuter from the Saldidae family, 1870, was first recorded in Kazakhstan. By trophic links, zoophages predominate - 40 species, 60%; zoophytophages - 27 species, 40%. According to their association with habitats, aquatic hemiptera are subdivided into several groups: periphyton, nekton, pleiston, and supralittoral. Depending on the number of offspring per year, aquatic hemiptera of the Charyn State National Research and Production Enterprise is divided into three groups, which means that the number of species that reproduce several times a year is 13 (19%), twice a year - 8 species (12%), one once a year - 46 species (69%). Stages of wintering of aquatic hemiptera: adults - 59 species (88%), larvae - 3 species (5%), eggs - 5 species (7%). Key words: aquatic hemiptera, Charyn State National Natural Park, South-East Kazakhstan.
