For their normal living, honey bees (Apis mellifera) require proteins, carbohydrates, lipids, vitamins and minerals. It is well known that Co and vitamin B12 are two nutrients that have been reported in pollen and plants that have had positive results in bees feeding. In this respect, the aim of the study is to determine the influence of feeding of the bee families with CoSO4 as a supplement on...

The hive of the honey bee is a suitable habitat for diverse mites (Acari), including nonparasitic, omnivorous, and pollen-feeding species, and parasites. The biology and damage of the three main pest species Acarapis woodi, Varroa jacobsoni, and Tropilaelaps clareae is reviewed, along with detection and control methods. The hypothesis that Acarapis woodi is a recently evolved species is rejecte...

A novel feeding protocol for delivery of bio-active agents to Varroa mites was developed by providing mites with honey bee larva hemolymph supplemented with cultured insect cells and selected materials delivered on a fibrous cotton substrate. Mites were starved, fed on treated hemolymph to deliver selected agents and then returned to bee larvae. Transcript levels of two reference genes, actin a...

Although sublethal dosages of insecticide to nontarget insects have never been an important issue, they are attracting more and more attention lately. It has been demonstrated that low dosages of the neonicotinoid insecticide imidacloprid may affect honey bee, Apis mellifera L., behavior. In this article, the foraging behavior of the honey bee workers was investigated to show the effects of imi...

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...

abstract: mostly honey bee consumes pollen as fermented and fermentation improves foods biological value in some cases.  in this study we evaluate the nutritional effects of fermented diets on honey bee body protein and brood rearing in colonies. this experiment conducted on honey bee colonies with different diets in a completely randomized design with 6 treatments and 7 replicates for 50 days....
