The karyotype of the aphid Aphis sambuci has been studied by means of C-banding, fluorochrome staining and AgNO3 staining. Heterochromatic areas are confined exclusively to the X chromosomes. Interestingly, silver staining produces a clear-cut longitudinal differentiation of all chromosomes, which allows reliable identification of homologues.

Abstract
The karyotype of the aphid Aphis sambuci has been studied by means of C-banding, fluorochrome staining and AgNO3 staining. Heterochromatic areas are confined exclusively to the X chromosomes. Interestingly, silver staining produces a clear-cut longitudinal differentiation of all chromosomes, which allows reliable identification of homologues.
