[Effect of larval feeding and imaginal supplementary nutrition on the degree of autogeny and fertility of Culex pipiens molestus mosquitoes at different periods of the year].

Studies of ovogenesis of C. p. molestus at different food regimes (water, sugar, blood) have shown that in winter the imaginal feeding with carbohydrates nearly twice increases the degree of autogenity and fecundity of these mosquitoes. In warm seasons the carbohydratous feeding does not affect the autogenity but increases the fecundity of females and maturation of their ovaries. Poor larval feeding decreases only slightly the autogenity and sharply decreases the fecundity of females. Blood feeding favours the maturation of ovaries in most members of C. p. molestus and the growth of their fecundity.
