Abstract: The morphology of mitotic chromosomes from brain tissues of forth-instar larvae has been studied in eleven genera and thirty five species of mosquitoes presented in China. There included 4 of Anopheles, 7 of Aedes, 13 of Culex, 2 each of Armigeres, Uranotienia and Topomyia, one each of Heizmania, Othopodomyia, Malaya, Tripteroides and Toxorhynchites. The Chromosome preparation techniques used before have now been improved by the Giemsa staining techniques. A comparison of the mitotic figures among the eleven genera and thirty five species is provided in generic and specific differences analyisis. The variance among the four species of Anopheles was analyized with Q-test. The results are as follows: 1.The differences of the mitotic figures among the four species of Anopheles are highly significant. 2.The brain tissue somatic paring in all the three pairs of chromosomes during prophase is common, except No.1 chromosomes of male Anopheles in some of species, the doubled chromosomes seemed presented untill the early metaphase. 3.The total length of chromosomes is different in various genera and appears to be a generic characteristic. The karyotypes of Hei zmania, Topomyia and twenty two species are described for the first time and those of seven genera and thirty species are first described in China.
