Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The article shows the list of species diversity of the family Simuliidae, noted in Pavlodar Priirtyshye in the period from 2022 - 2024. In the basin of the middle reaches of the Irtysh River (from the border of the Maysky district to the Zhelezinsky district, the border with Russia), the presence of 5 species of blackflies was noted. The identified blackflies belong to the Palaearctic and Holactic 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 in the studied area is noted. The frequency of occurrence is indicated, and the bionomics of species for the Pavlodar region is described. Dominant species are identified.
