Blood-sucking diptera insects (insecta: diptera) Tyumen region.

The territory of the Tyumen region is located in the West Siberian Lowland and is characterized by conditions favorable for the development of blood-sucking diptera insects. The fauna of the blood-sucking diptera insects of the Tyumen region is represented by 109 species and 4 subspecies: horseflies-35 species and 4 subspecies, mosquitoes-41 species, blackflies-16 species, biting midges-17 species. In the subzone of the southern taiga, Hybomitra ciureai, H. bimaculata, H. lundbecki, H. muehlfeldi, Haematopota pluvialis, Aedes cantans, A. punctor, Simulium maculatum, Culicoides punctatus dominate; in the subzone of aspenbirch forests-Tabanus bromius, Hybomitra ciureai, H. bimaculata, H. lundbecki, Atylotus fulvus, A. rusticus, Haematopota subcylindrica, H. pluvialis, Aedes cinereus, A. punctor, A. cantans, Simulium pusillum, Culicoides punctatus; in the forest-steppe zone-Tabanus bovinus, T. bromius, Hybomitra ciureai, H. bimaculata, H. lundbecki, Haematopota pluvialis, H. subcylindrica, Coquillettidia richiardii, Aedes caspius, A. albescens, A. cantans, Simulium maculatum, Culicoides punctatus. The total summer period of insects of this group ranges from 140 days in the subzone of the southern taiga to 170 days in the forest-steppe zone. Depending on the meteorological conditions of the spring-summer season, the start and end dates of summer may shift by 1-2 decades. The activity of horseflies and blackflies is observed during the daytime, and mosquitoes and biting midges are twilight insects and attack mainly in the morning and evening hours. The main abiotic factors determining the nature of the diurnal rhythm of the vital activity of diptera insects in the conditions of the Tyumen region are air temperature and illumination.
