[THE CYTOGENETIC CHARACTERISTIC OF SOME PALEARCTIC POPULATIONS OF HOLARCTIC MIDGE GLYPTOTENDIPES BARBIPES STAEGER (DIPTERA, CHIRONOMIDAE)].

Set and frequencies of inversion banding sequences in polytene chromosomes in the Palearctic natural populations of a Holarctic chironomid Glyptotendipes barbipes (2n = 8) (the Northwest of Russia, Irkutsk region, Kirghizia, Armenia) have been investigated. The majority of larvae were heterozygotes on inversions. Distinctions in a set and frequencies of inversions between populations form different regions have been ascertained. We have established that G. barbipes karyotype in the populations studied includes inversion banding sequences that are endemic for Palearctic (p'barG2), and also the general sequences met both in Palearctic, and in Nearctic (h'barB3, h'barC3, h'baE2, h'barF2).
