| Summary: | The chromosomal variability of Anopheles messeae Fall. mosquitoes were studied in six settlements of Tomsk oblast (Western Siberia). The frequencies of chromosomal inversions in local samplings of An. messeae were determined. The prevalence of inversion variants of autosomes was established: 2R(0), 3R(0), 3L(0) in a homozygous state. An excess of heterozygotes for XL01 was noted in the studied samplings on the sex chromosomes XL. Apparently, selection toward chromosomal variants XL01, 2R(00), 3R(00), and 3L(00) in Tomsk oblast of An. messeae can be explained by climatic changes in recent decades, creating optimal conditions for the growth and development of mosquitoes. |
