[Biology of mosquito Aedes impiger (Culicidae) and its possible role as a phenological indicator]

The biology of Aedes impiger Walk. from the polar region of the European part of the USSR has been studied and literary data have been summarized. Its biological peculiarities such as rapid and simultaneous development of larvae and pupae, a short period of seasonal activity, long daily activity, the presence of autogeny and long obligate diapause provide a distinct localization of the active period of the life cycle within a season. A. impiger develops quicker than other spring species of mosquitoes, emerges the first and can serve as phenoindicator for specification of developmental periods and mass emergence of bloodsucking mosquitoes.
