Abstract
In 1974 and 1975, mosquitoes were collected from eight locations
considered representative of three distinct ecological zones in
Saskatchewan and Keewatin District, N.W. T. - the grasslands, the
boreal forest, and the tundra. The geographic and seasonal
distribution of mosquitoes and their habitats are described and notes
are given on the 35 species. The environmental conditions that
determined species distribution are also discussed and it is suggested
that the rate of snowmelt in the spring and the amount of snow or
rain determines the date and extent of egg hatching. The temperature
of the water and air determines the rate of development of the eggs,
larvae and pupae, the rate of ovarian development in the adult
females and the general level of activity in adults. Distribution
does not appear to be affected by water quality or the presence of
parasites and predators. From this information it was possible to
forecast mosquito distribution and abundance, especially on a local
scale.
