Using the method of microdissection of polytene chromosomes, followed by in situ hybridization, chromosomal localization of region-specific DNA probe from pericentic heterochromatin of chromosome 2L of Anopheles beklemishevi Stegnii et Kabanova was examined on polytene chromosomes of Anopheles atroparvus van Thiel, An. messeae Fall, and An. beklemishevi. DNA sequences homologous to the probe used were found in all species examined on chromosomes 2 and 3 in pericentric regions and in attachment regions. The exclusion were the attachment regions of chromosome XL in An. beklemishevi and An. messeae, and pericentric region of arm 2R in An. messeae. Pericentric α -heterochromatin of arm 2L in An. messeae and arm 3R in An. atroparvus also contained no sequences homologous to the DNA probe. The data obtained were compared with the earlier obtained data on localization of species-specific probe from the segment of chromosome 2R of An. atroparvus on chromosomes of An. artoparvus, An. messeae, and An. beklemishevi. The differences between the species in the sites of probes localization and fluorescence intensity revealed pointed to the existence of individual sequence associations in the regions of chromosomes attachment.
