Abstract

Chromosomes from gonads of 14–24 h old pupae of nine species of Stegomyia mosquitoes have been examined using the Giemsa C-banding technique. The species studied were Aedes albopictus, A. polynesienis, A. scutellaris, A. alcasidi, A. seatoi, A. pseudalbopictus, A. melallicus, A. annandalei and A. vittatus. The diploid chromosome number of all species is six. All species possess C-bands in the centromeric regions of each of the three pairs of chromosomes. Besides, 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. Thus, the nine species of Aedes analysed showed two distinct patterns of C-banding. —The evolution of heterochromatin patterns in various species is also discussed. The Giemsa C-banding technique should prove useful in studies of chromosomal speciation in culicine mosquitoes.
