Diversity and seasonal dynamics analysis of the blood-sucking mosquitoes fauna (Diptera, Culicidae) of the Tavdinsky district of the Sverdlovsk region

This article provides data on the species diversity and seasonal dynamics of blood-sucking mosquitoes (Diptera, Culicidae), which are important vectors of various infectious and invasive diseases. As a result of the research conducted during several seasons from 2020 to 2022, it was revealed that 11 species of mosquitoes belonging to the genera Anopheles, Aedes and Culiseta live on the territory of the Tavdinsky district of the Sverdlovsk region. When comparing the number of culicids for all seasons, a correlation was revealed between hydrological, weather conditions and the intensity of insect summer. The optimal level of precipitation during the year provides enough breeding sites for mosquito larvae. The 2022 season was favorable for the development and summer of mosquitoes, in which heavy precipitation contributed to a vast area of reservoirs necessary for the development of insects. The smallest number was observed in 2021. As a result of low rainfall, severe frosts in winter, cold spring and arid, hot summer, there was a reduction in the number of mosquitoes. The results of the study allow a deeper understanding of the ecology of mosquitoes in this region, their activity in different seasons and their potential role in the transmission of infections. This work is important for the development of effective strategies for controlling mosquitoes and preventing diseases associated with their bites.
