Abstract: 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: 2R₀, 3R₀, 3L₀ 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, 2R₀₀, 3R₀₀, and 3L₀₀ 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.
