The Southern Urals of Russia are the habitat of one of the surviving populations of the dark forest bee—the Burzyan population of Apis mellifera mellifera. In this study, we present the results of the subspecies identification of bee colonies in the Altyn-Solok Nature Reserve in the Southern Ural Mountains using the intergenic mtDNA COI-COII locus and the assessment of the prevalence of nosematosis. Analysis of the mtDNA COI-COII intergenic locus in the studied sample showed that 30.4% of the co...

Given is an overview of original publications devoted to the investigation of the honey bee genome. The history of honey bee genome studies and its characteristics are described. The results of genetic studies of honey bees using genome-wide data are presented. A special focus is put on the search for alleles associated with economically valuable, adaptive, and other important honey bee traits.

In honey bees, sex is determined by an allelic combination of the csd gene. Low allelic diversity for the csd gene leads to a loss of colony strength due to the appearance of nonviable diploid drones from eggs homozygous for the csd gene. Therefore, there is a need in beekeeping to identify and monitor the allelic diversity of the csd gene. In this paper, we present the results of the polymorphism analysis of the hypervariable region of the csd gene in the local population of Apis melliferamelli...

The effect of chitosan (200 kD, 75% deacetylation) on Nosema apis development in bee colonies during wintering was investigated. The conditions for development of the nosematous infection were analyzed. According to the results of determination of PCR products specific for N. apis, chitosan decreased significantly the degree of infection of individual bees with N. apis spores. The scheme of stimulation of the bee immune system by chitosan via the changes in the level of antimicrobial peptides an...

High-molecular weight chitosan (200 kDa, 75% deacetylated) and N-succinoyl chitosan (300 kDa, 75% deacetylated) were shown to have a preadaptive effect and increase the lifespan of honeybees due to the induction of protective antioxidant and immune mechanisms. Chitosan with a molecular weight of 200 kDa had a fungistatic effect on a pathogenic fungus that causes ascospherosis, a disease of bee larvae and pupae.

Specific conditions of the honeybee life honeybee life require the presence of effective mechanisms of antiinfectious protection whose one of the most important components are defensins—the family of antimicrobial peptides. In the honeybee, defensins are present in the form of two different peptides—defensin 1 and 2 that are similar between each other only by 55.8%. Defensin 1 synthesized in salivary glands plays an important role in social immunity, whereas defensin 2 synthesized by cells of fa...

The work deals with the effect of population density on the functional activity of humoral immunity components in adult and immature cockroaches. Immune resistance has been found to decrease in individuals maintained singly as well in those under overpopulation pressure. Changes in enzyme activities of the antioxidant and phenol oxidase systems were studied in hemolymph and intestine of the insects. Possible consequences of isolation and overpopulation both for immunity and for individual develo...

: The work deals with effect of density of population on functional activity of components pf protective system of adult individuals and nymphs of the marble cockroach. The resistance of individuals has been noted to decrease both at individual maintenance and under conditions of overpopulation. Changes in activities of enzymes of antioxidative and phenoloxidase systems are studied ion the insect hemolymph and intestine. Possible consequences of isolation and overpopulation are discussed both fo...
