title: [Inversion polymorphism of Glyptotendipes glaucus Mg. (Diptera: Chironomidae) from the reservoirs of Kaliningrad].
abstract: The karyotypes of larvae Glyptotendipes glaucus Mg. 1804 from three reservoirs of Kaliningrad city (Pen'kovoe and Karasevka lakes and Chistyi pond) were studied. The levels of the natural inversion polymorphism for the three populations were determined. Ten new inversion sequences (gla B4, gla B5, gla B6, gla D5, gla E4, gla E6, gla E7, gla F6, and gla F7) were detected in the species studied. Inversion including the centromeric region in IIIEF (gla E6 + gla F7) was pericentric. Several cases ofgla B5 and gla B6 combination with gla B2 resulting in genotypic combination gla B2.5 and gla B2.6 were found. The dependence of the number of inversion sequences and genotype combinations from the content of heavy metal ions in sediments of the reservoirs was revealed. All populations were characterized by the prevalence of inversion sequence gla B2 in chromosome I.
