Treatment

Chironomus dorsalis sensu Strenzke View in CoL

The chromosome set is 2n = 8.AE chromosome is submetacentric, CD and BF chromosomes are metacentric, G chromosome is telocentric ( Fig. 16 View FIGURE 16 ). The centromere regions of all chromosomes are formed of thin dark bands. Chromosome G has two BRs and one NOR, near to the centromere region. On both sides of one BR there are double dark bands—a marker of the species ( Fig. 16 View FIGURE 16 ).Ten larvae were analyzed.

Collection sites: Sofia: Pancharevo Lake , Gornja Banij; Chepelare: fish pool .

FIGURE 16. Polytene chromosomes of Chironomus dorsalis. The numbers on the chromosome arms indicate the “basic”sequences.The large arrows show the localization of the centromere region. The small arrow on chromosome G indicates the marker sequences required for species identification. BR—Balbiani Ring, NOR—Nuclear Organizer Region. A, B, C, D, E, F, G—arms of the chromosomes.
