SEASONAL ACTIVITY AND POPULATION DYNAMICS OF CULICIDAE MOSQUITOES IN THE AQUATIC ENVIRONMENT OF THE REPUBLIC OF DAGESTAN

Abstract

Aim. The central aim of the article is to study the phenological dates of activity of culicidae mosquitoes in Dagestan during the season and seasonal density dynamics taking into account the changes of climatic conditions.Methods. We used netting and the standard five-minute method of sampling of adult mosquitoes at roost sites every four days throughout the season. Preimaginal phases of mosquitoes were examined in the test reservoirs of different types using fotokyuvet.Findings. The analysis of the study showed that the studied area is inhabited by 19 species of mosquitoes, including Anopheles maculipennis and Culex pipiens pipiens are most widespread. At the same time, the seasonal timing of activity is extending.Conclusion. In Dagestan, there are three conditions, lifting the number of mosquitoes during the spring-summer season: during the last ten days of May, the end of the second ten days of June and the beginning of the first decade of September. The first rise in the number is associated with the spring rains and the rivers flood, the second with the spills of irrigation systems, and the third with autumn floods and favorable weather conditions.
