Preliminary results of the study of interrelation of karyotype structure of non-biting midges of genus Chironomus (Diptera, Chironomidae) with environment factors in the Central Caucasus

The preliminary results of the study of interrelation of karyotype structure of non-biting midges of genus Chironomus (Diptera, Chironomidae) with environmental factors in the conditions of the Central Caucasus are presented. The obtained data allow us to conclude that the largest degree of interrelation of karyotype structure can be traced to such environment factors as, temperature in the middle of April and July, t average annual, forest-forming species, altitude and transparency of water. Different genotypic combinations exhibit varying degrees of correlation with environmental factors. In general, karyotype structure shows a significant negative correlation with temperature factors.
