Revision of the banding sequence pool and new data on chromosomal polymorphism in natural populations of Chironomusagilis Shobanov et Djomin, 1988 (Diptera, Chironomidae)

Quantitative and qualitative analysis of chromosomal polymorphism in 19 natural populations of Ch.agilis had been performed. Most studied populations showed a medium level of chromosomal polymorphism: on average 45±3.0% of specimens are heterozygotes with 0.52±0.01 heterozygotic inversion per larvae. Besides inversions, B-chromosomes were found in two populations. The total number of banding sequences found in banding sequence pool of Ch.agilis is 16. Three banding sequences - p'agiB3, p'agiD3, p'agiF3 - are described for the first time.
