The fauna of blood-sucking mosquitoes of Belarus consists of 40 species belonging to 5 generas (Anopheles - 5, Culiseta - 5, Coguilletidia -1, Aedes - 25, Culex - 4). On the urban landscapes there were registered 29 species from 4 generas (Anopheles, Culiseta, Aedes, Culex), among them 19 species were registered in villages, 27 species were registered in middle towns and 24 species were registered on the territory of large industrial towns. The peculiaritis of the influence urbanization on the structure faunistic complexs of blood-sucking mosquitoes were studed. It is revealed, that character of influence of urbanization on formation of specific riches and dynamics of number of blood-sucking mosquitoes depends on a degree of a urbanization and is aimed at different directions. The initial degree of urbanization leads to increase in concrete fauna of mosquitoes in comparison with their fauna on forbidden territories. The high degree of urbanization causes impoverishment of specific structure up to individual kinds (a zone of multi-storey building). When insects urbanization assimilating the tendency to change the status of number of blood-sucking mosquitoes at kinds of 3 and 4 groups is noted. Kinds of intrazone and zone fauna for the first time are revealed in urbanolandscape. Zoogeographycal analysis has shown, that the fauna of blood-sucking mosquitoes of the urbanized territories is basically presented by holarctic and palearctic elements. On inside city territories the increase in number of holarctic kinds and decrease in quantity of palearctic kinds, except for a park zone, with absolute domination of cosmopolitan kind (Сх pipiens L.) at increase in a degree of urbanization
