Wingbeat Frequencies of Some Anopheline Mosquitoes of East Asia(Diptera : Culicidae)

Abstract

The wingbeat frequencies were studied of some anopheline mosquitoes including vectors of human malaria and filariasis in East Asia. These frequencies showed low values in newly emerged of both sexes, and rose with increasing age during the first 2 days after emergence. Thereafter, the frequencies were maintained at high constant levels for more than several days. The wingbeat frequency of a mated female was not significantly different from that of a virgin female of the same age, while there was a slight difference between a blood-fed female and a non blood-fed one. There was a correlation between wingbeat frequency and wing length in each sex among the 13 colonies of 8 species. The wingbeat frequencies of mosquitoes in a colony varied widely and the standard errors of the mean frequencies overlapped among species and taxa.
