Local honeybee (Apis mellifera mellifera L.) populations in the Urals

Russian Journal of Genetics, 2007
The COI-COII intergenic region of mitochondrial DNA (mtDNA) was studied in local honeybee (Apis mellifera mellifera) L. populations from the Middle and Southern Urals. Analysis of bee colonies in these regions revealed apiaries enriched in families descending from A. m. mellifera in the maternal lineage.

Glyphosate-based herbicides and Nosema sp. microsporidia reduce honey bee (Apis mellifera L.) survivability under laboratory conditions

, 2020
Reduction in the population of pollinators can compromise the stability of natural and agricultural ecosystems. One cause of this reduction is contact between pollinators and pesticides.

[Intestinal enterobacteria of the hibernating Apis mellifera mellifera L. bees].

Mikrobiologiia, 2008
Dynamics of enterobacteria of normal intestinal microflora was studied in Apis mellifera mellifera L. bees hibernating under snow in the Western Urals. The cell numbers (N) of the predominant species Klebsiella oxytoca increased from 10-10(6) CFU/bee in November 2004 to 10(4)-10(7) CFU/bee in March 2005; its frequency of occurrence (P) increased from ...

Male fitness of honeybee colonies (Apis mellifera L.)

Journal of Evolutionary Biology, 2003
Abstract Honeybees (Apis mellifera L.) have an extreme polyandrous mating system. Worker offspring of 19 naturally mated queens was genotyped with DNA microsatellites, to estimate male reproductive success of 16 drone producing colonies.

Learning in the Africanized Honey Bee: Apis mellifera L.

Physiology & Behavior, 1997
Several series of experiments are reported that investigate learning in the Africanized honey bee. In the first series, classical conditioning of proboscis extension was studied by confining bees to small metal tubes where they received pairings of an odor with a 3-s feeding of sucrose.
