9个种14-24 h蛹期性腺的染色体。用Giemsa C[组成型异染色质]-显带技术检查了伊蚊的染色体。所研究的物种是A. albopictus、白纹伊蚊A. polynesiensis，A. scutellaris、盾叶甲A. alcasidi、黑腹滨藜A. seatoi、黑腹拟步行虫A. pseudalbopictus、拟白纹伊蚊A. metallicus、A. annandalei和A. vittatus。所有种的二倍体染色体数目均为6。所有物种的3条染色体的每个巴黎的着丝粒区域都具有C带。除A外，所有种的雌性决定染色体（= m）上都有一插入C带，而雄性决定染色体（= M）上均无。vittatus。以. m和M染色体具有一条末端C带。9 spp。结果表明，有2种不同的C-带型。异染色质模式在不同物种的进化进行了讨论。Giemsa C-显带技术在库蚊染色体形态研究中是有用的。
Chromosomes from gonads of 14-24 h old pupae of 9 spp. of Aedes mosquitoes were examined using the Giemsa C[constitutive heterochromatin]-banding technique. The species studied were A. albopictus, A. polynesiensis, A. scutellaris, A. alcasidi, A. seatoi, A. pseudalbopictus, A. metallicus, A. annandalei and A. vittatus. The diploid chromosome number of all species is 6. All species possess C-bands in the centromeric regions of each of the 3 paris of chromosomes. An intercalary C-band is present on the female determining (= m) chromosome but absent from the male-determining (= M) chromosome of all species except A. vittatus. In A. vittatus, the m and M chromosomes possess a terminal C-band. The 9 spp. of Aedes analyzed showed 2 distinct patterns of C-banding. The evolution of heterochromatin patterns in various species is discussed. The Giemsa C-banding technique should prove useful in studies of chromosomal speciation in culicine mosquitoes.
