| Summary: | Introduction. Blood-sucking mosquitoes (Diptera, Culicidae) are an important compo- nent of ecosystems. They contribute to the transmission of dangerous pathogens such as West Nile fever (WNF), malaria, tularemia, etc. therefore, monitoring of blood-sucking mosquitoes, studying the geographical distribution, their biology, ecology, biocenology, physiology and pathogenic significance is a task of the theoretical and epidemiological vector. Stavropol Territory is one of the regions with a high risk of malaria importation and the formation of local foci. According to the potential risk of malaria transmission, the region can be divided into three zones. The first is a zone of sustained risk of malaria transmission; the second is a zone of moderate risk; the third is a zone of low risk. Material and methods of research. The material for this work was the results of field studies, collecting mosquitoes in natural biotopes of various landscapes from May to September in different seasons of 2015-2017 by mowing with a net, by catching "on yourself "[6], in the room with a "test tube", collecting eggs and larvae of 1 - 4 ages from reservoirs. In total, more than 5 thousand imago and larvae of mosquitoes were caught and identiied. To determine the species identity, the guidelines of Gutsevich and co-authors (1970) and Gornostaeva and Danilov (1999) were used [1, 3, 10]. During the analyzed period, 16 territories of the region were surveyed in the reservoirs of which the preimaginal stages of mosquitoes were monitored, we selected more than 2500 water samples. The greatest abundance of larvae per mA2 (more than 50 specimens) was observed in the Kirovsky and Shpa-kovsky districts. Results and their discussion. As the results of the study, a list of blood-sucking mosquitoes is presented, compiled on the basis of our own research and literature data on the location of certain Culicidae species in the Stavropol Territory [4,5,7,8]. The names of taxonomic categories are given in accordance with recent publications of domestic and foreign authors [1, 9, 11]. The species composition of blood-sucking mosquitoes in the study area is represented by eight genera: Anopheles Meigen, 1818; Uranotaenia Lynch Arribalzaga, 1891 ;Culiseta Felt, 1904; Aedes Meigen, 1818; Dahliana Reinert, Har-bach & Knelling, 2006; Ochlerotatus Lynch Arribalzara; Culex Linnaeus, 1758; Coguillettidia Dyar, 1905 Conclusions. In all landscapes of the Stavropol Territory, the largest number of species belongs to the genus Ochlerotatus (10), which is typical not only for the blood - sucking mosquito fauna of the Stavropol Territory, but also for the Culicidae fauna of Russia as a whole [2, 9]. No more than 12 species of blood-sucking mosquitoes can be considered background species, and the following species of mosquitoes-Anopheles hyrcanus, Anopheles maculipennis, Culex modestus, Cx.pipiens pipiens, Coquillettidia richardii and Aedes mosquitoes. Blood-sucking mosquitoes are of great medical importance, being carriers of common infections, including malaria. The main breeding sites for malaria mosquitoes are reservoirs, ponds, lakes, streams, wetlands in floodplains, old rivers, spring mochaks, and a developed irrigation network. In this regard, it is necessary to carry out timely certification of reservoirs. |
