Karyotypes of Aedes (Culicidae) mosquitoes (Ae. excrucians, Ae. behningi, and Ae. euedes) have been analyzed using the metaphase chromosomes of imaginal discs. Lacto-aceto-orcein, C-banding, and DAPI staining have detected species-specific features in the morphology and lengths of these chromosomes in the examined species. Species-specific features of chromosome 1 in the location of heterochromatin blocks have been shown. Thus, the metaphase chromosomes in the imaginal discs of Ae. excrucians, Ae. behningi, and Ae. euedes are a characteristic for species identification of mosquito species.
Keywords: Aedes; Blood-sucking mosquitoes; C-banding; Culicidae; DAPI; heterochromatin; imaginal discs.; lacto-aceto-orcein; mitotic chromosomes.
