Abstract: The present paper is the results of ANOVA analysis and canonical discriminant analysis of morphological characters of hybrid larvae obtained from hybridization between members in Culex pipiens complex and their parents. It was found that there were significant differences among hybrids and their parents in siphonal index, branches of the first and second pair of siphonal tufts(1-S). These characters of the hybrids were intermediate between their parents.

Key words: Culex pipiens complex, hybrids, siphonal index, the first 1-S, the second 1-S
