[Nocturnal biting activity of mosquitoes (Diptera, Culicidae) in Volgograd and its environs]

The nocturnal biting activity of mosquitoes was investigated by a Berezansev's bell and bird traps as baits in August 2003. Among 7 man-attacking species, C. modestus, C. pipiens, and Coq. richiardii were most abundant. C. pipens showed two peaks of biting activity at night while both C. modestus and Coq. richiardii displayed one peak of this activity. Bird traps attracted the mosquitoes C. pipiens and C. modestus. The results are discussed in terms of the possible involvement of the above species in the transmission of WNF virus in Volgograd and its environs.
