[Population of the mosquitoes Culex pipiens molestus (Diptera: Culicidae) in dwellings of Lensk city].
Culex pipiens molestus has been distributed in Siberia and the Russian Far East since 80s of XX century. In early 90s, C. p. molestus reached South Yakutia (Nerungri city), and nowadays it occurs in South-West Yakutia (Lensk city). The number of breeding places with larvae and pupae of mosquitoes was not numerous in Lensk; among 56 examined houses, the places with larvae and pupae mosquitoes were registered in seven houses, while the adult mosquitoes occurred in the majority of the houses. The occurrence of larvae varied from 12.5 to 33.3%, occurrence of adults-from 12.5 to 100%. The coefficient of variation of larvae in the samples was equal to 0.92, and adults had the following coefficients: 0.84 in the houses without basement; 0.92 in the houses with dry basements; 1.05 in the houses with pools in basements. This data are referred to the casual type, it means that the distribution of mosquitoes in space is dispersed. Imago spread actively in stone house of Lensk that provides mosquitoes with new places of breeding, and supports the stability of population in new areas.
