Distribution of blood-sucking mosquitoes (Diptera, Culicidae) to various biotopes in the south of Tyumen territory

The spread of mosquitoes and their preference of different habitats to the habitat and the attack on proximately defined primarily by ecological charac-teristics of individual species, namely moisture-preferance and resistance to aridity. Moisture- loving species attack mainly under the forest cano-py and are confined to the Northern regions with large areas of forests. The Study of species com-position and biotopical distribution of mosquitoes was conducted in the southern taiga subzone and aspen-birch forests of the forest zone and in forest-steppe zone of the Tyumen territory in 2004-2014. Ecological requirements of different species vary, so they inhabit different vegetation composition of habitats. Arid-resistant species generally prefer forest edges, meadows and common in the south-ern zones, where forests occupy a small area. The work was carried out two times a decade in the evenings at 19-20 o’ clock. To determine the spe-cies composition of adult Culicidae mosquitoes special identification keys were used with the re-lease of the subgenus Ochlerotatus in the rank of genus. All species of mosquitoes of the investigat-ed region can be divided into three groups: 1) the attackers only under the forest canopy; 2) forwards only in an open area; 3) actively forwards in both habitats. The majority of species of blood-sucking mosquitoes on the South of Tyumen territo-ry attacks under the forest canopy and in open are-as. The greatest ecological plasticity in relation to inhabiting different biotopes has Och. cantans.
