Prevalence of the Microsporidian spp. in Honey Bee Populations () in Some Ecological Regions of North Asia.

Two species of microsporidia, and , are obligate intracellular parasites that are widespread in the world and cause the infectious disease (Nosemosis) of the Western honey bee . 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.

INFESTATION OF HONEYBEE (APIS MELLIFERA) FAMILIES BY MICROSPORIDIANS OF THE GENUS NOSEMA IN TOMSK PROVINCE.

Infestation of bee colonies and apiaries by representatives of the genus Nosema, microsporidian protozoans of European honeybees (Apis mellifera L.), causing nosemosis, in Tomsk Province was investigated. In 2012—2015, nosemosis was detected in 32 out of 124 honeybee colonies (31.

[Genetic diversity of the locus COI-COII of mitochondrial DNA in honeybee populations (Apis mellifera L.) from the Tomsk region].

An assessment of the genetic diversity of the COI-COII mtDNA locus in honeybee populations from the Tomsk region was conducted. 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.
