To the question of current species composition of blackflies (Diptera, Simuliidae) of the Irtysh river in Pavlodar region

Abstract

The article presents a list of species diversity of the family Simuliidae identified in the Pavlodar Priirtyshye during the period from 2022 to 2024. In the basin of the middle reaches of the Irtysh River (from the border of the Maysky district to the Zhelezinsky district, and the border with Russia), the presence of 5 species of blackflies was noted. The identified blackflies belong to the Palaearctic and Holarctic species of plastic blackflies capable of living in polluted water bodies: Wilhelmia equine (Linnaeus, 1758), Boophthora erythrocephala (De Geer, 1776), Odagmia ornata (Meigen, 1818), Argentisimulium noelleri (Friederichs, 1920), Simulium reptans (Linnaaeus, 1758). The history of the study of blackflies in Kazakhstan and the studied area is presented. The frequency of occurrence and the biology of the species in the Pavlodar region are described. Dominant species are identified.
