Abstract: Wing and leg Length distributions of Culex tritacniorhynchus Giles fcmales in pre-hiberna tion(Oct. -Nov.) were found to include two different component groups with regard to wing and leg length. One was a long-winged group which accounted for about 46.6% of all the population, and the other was a shortwinged group making up 53.4% (Table 2). Wing and leg length distributions of the females did not prove to be the normal patterns using probability paper analysis for frequency distributions. The wing length of the nulliparous females was longer than that of the parous ones in prehibernation. Gonotrophic dissociation of the short-winged group was higher than that of the long-winged ones. The wing and leg length ot the females didn't related to the blood-fed activity and mating. Observations on ovarian development of both wing length females show that the females almost were in a non-diapause.
