[Biology of biting midge species (Ceratopogonidae) in the southern Krasnoyarsk Territory].
In the valley of the Enisei (140 km from the town of Abakan up to the river) C. sinanoensis and C. sanguisuga are mass bloodsuckers while C. chiopterus and C. filicinus occur in small number. Data on the age composition of attacking females confirm the autogeny of C. filicinus and suggest the presence of autogeny in C. chiopterus. C. sinanoensis and C. sanguisuga can have two generations during the period of their activity. The emergence of the 1st generation takes place in the IInd--IIIrd decade of June, the emergence of the 2nd generation--at the beginning of August. The 2nd generation is so small, as a rule, that its appearance does not practically affect the abundance of attacking females. C. sanguisuga is less sensitive to light and attacks at a somewhat higher temperature as compared to C. sinanoensis. As a result, a morning peak of abundance of C. sanguisuga takes place in 1--2 hours after the peak of abundance of C. sinanoensis while the evening peak is 1--2 hours prior to it. The daily period of activity of C. sanguisuga is usually longer than that of C. sinanoensis.
