Abstract. Studying the regulated runoff of the Volga River as one of the factors influencing the development of blood-sucking midges of the Simuliidae family in the Lower Volga region is an important component of the overall study of the phenological developmental characteristics of this dipteran insect species. The article presents comparative data from phenological observations of blood-sucking midges of the Simuliidae family in the Volgograd region before the regulation of the Volga River flow by the Volga Hydroelectric Power Station dam in 1957–1958, observation data for the period 1961–1969 (after the hydroelectric power station was commissioned), and in the modern period. An analysis of the discharge flow regimes of the Volga Hydroelectric Power Station during the spring floods of 1961–1969 and 2020–2024 was carried out. The dependence of the dynamics of the seasonal abundance of blood-sucking midges on the duration of high water and its levels has been established. Analysis of previous and current research on the impact of Volga River flow regulation on blood-sucking midges of the Simuliidae family is of great practical importance in developing measures to regulate their populations in the Lower Volga region.
Key words: hydrological regime, regulated runoff, water bodies of the Volga basin, Volga Hydroelectric Power Station, blood-sucking midges, family Simuliidae, Volgograd region.
