background: the american foulbrood disease (afb), caused by paenibacillus larvae subsp. larvae, is one of the main plagues affecting honey bee (apis mellifera l.) colonies, and it has a high negative impact on beekeepers worldwide. objectives: the aim of this research was to describe the evidence of paenibacillus larvae larvae contamination of honey bee colonies, in the east azerbaijan province...
Background: Due to its nutrient content, a variety of spoilage microorganisms can grow in bee pollen, especially when handling practices are not appropriate. So, this survey was designed to assess the physicochemical and microbiological properties of bee pollen collected from Bulgaria. Methods: In June 2014, 13 fresh and 19 dried bee pollen samples were collected from Bulgaria. Water activity ...
acute bee paralysis virus (abpv) is a small single stranded rna virus recently classified within the family dicistroviridae, genus cripavirus. here, we describe the first study of abpv in unhealthy bee colonies, which has been an unusual loss in adult bee population and significant honey bee mortality during the year. the aim of this study was evaluation of abpv infection in honey bee colonies ...

Carniolan bee (Apis mellifera carnica) and C phylogenetic lineage of honeybees as a whole, is genetically poorly studied, therefore, the genetic structure of Carniolan bee population from Slovenia has been assessed by mitochondrial and nuclear DNA analyses. Honeybees were collected from 269 localities in Slovenia; bee samples from Greece, Czech Republic, Croatia, Germany and France were include...
Extended Abstract Introduction and Objective: People are sensitive to bee venom and the presence of allergenic compounds in the venom has made it difficult to use and determine the optimal dose for treatment. The aim of this study was to reduce allergenic compounds and to evaluate the quality of gamma ray processed bee venom. Material and Methods: Venom samples were irradiated at dose...
The aim of the study was to estimate the impact of antibiotic doxycycline on the spring development of the bee colonies, worker bees’ bodies chemical composition, development of hypopharyngeal glands and some physicochemical parameters of honey. The experiment was conducted during the spring stimulating feeding at apiary of Research Center of Stockbreeding and Agriculture, Smolyan, Bulgaria. Tw...
Honey production from approximately 1.6 million colonies owned by about 199,000 Korean beekeepers was almost 23,000 metric tons in 2009. Nosema causes significant losses in honey production and the virus decreases population size. We initiated a survey of honey bee colonies on the blooming period of Acacia to determine the prevalence of Nosema and virus in 2011. Most Korean beekeepers have move...
Extreme winter losses of honey bee colonies are a major threat to beekeeping but the combinations of factors underlying colony loss remain debatable. We monitored colonies in two environments (colonies wintered indoors or outdoors) and characterized the effects of two parasitic mites, seven viruses, and Nosema on honey bee colony mortality and population loss over winter. Samples were collected...
