[Detection of chromosome races among the malarial mosquito Anopheles sacharovi]

Peculiarities of polytene chromosomes of populations of malarial mosquitoes Anopheles sacharovi from the Transcaucasus and Middle Asia were studied. It was established that karyotypes of specimens from the latter region differ from those from the formes in the inversions in chromosomes I and in the left arm of chromosome III. Since all the specimens examined proved to be homozygous towards the above inversions, the populations from the Transcaucasus and Middle Asia are reparated into chromosomal races.
