Simuliidae) are small dipterous insects from a suborder the long feelers are one of the most important components of the midges’ complex, midges are carriers of causative agents of various invasive and infectious diseases of people and animals. In this regard, the problem of studying features of ecology, specific structure is most actual in this region. The analysis of works of researchers in studying of fauna and ecology of blood-sucking midges (Diptera, Simuliidae) on three regions - Eastern Siberia, Western Siberia and the Far East is given. Huge social and economic transformations in Siberia and the Far East, the powerful accelerated region ur-banization, were a basis to expansion of large-scale actions for protection of the person and ani-mals from midges. On the territory of Asian part of Russian scientific institutions of biological, agricul-tural and veterinary profile coordination on entomo-logical researches are carried out. It was estab-lished by the authors that in general across Siberia specialists of 20 research establishments, higher education institutions, stations, laboratories were engaged in studying of midges. Analyzing a contri-bution of researchers and their publications, it is possible to draw a conclusion in studying of midges generally in the period of the USSR from the 1960-s to the 1980-s. Huge recession happened in the 1990-s and 2000-s. In the new millennium dynam-ics of increasing the number of specialists entomol-ogists showing a great interest in researches not only on blood-sucking midges and in all compo-nents of midges is revealed.
