Honeybees display a great range of biological, behavioral, and economic traits, depending on their genetic origin and environmental factors. The high diversity of honeybees is the result of natural selection of specific phenotypes adapted to the local environment. Of particular interest is adaptation of local and non-local bee colonies to environmental conditions.

One promising intervention approach is the breeding of -resistant honey bee colonies using molecular technologies, for example marker-assisted selection (MAS). For this, specific genetic markers used in bee selection should be developed.

Information on the prevalence and distribution of species in North Asia conditions is scarce. The main aim of the present study is to determine the prevalence of spp.

In 2012—2015, nosemosis was detected in 32 out of 124 honeybee colonies (31.

Three variants of the COI-COII mtDNA locus were registered: PQQ, PQQQ (typical for Middle Russian race), and Q (typical for southern breeds). It was established that 64% of bee colonies of the maternal line originate from the Middle Russian honeybee race, 28% of bee colonies originate from southern species, and 8% are mixed bee colonies.
