Morphometric analysis of the Carniolan Honeybee (Apis mellifera carnica) in the Republic of Srpska [PDF]

Agroznanje
Beekeeping plays a significant role in animal husbandry, providing valuable products such as honey, beeswax, royal jelly, pollen, propolis, bee swarms, queens, and pollination services, essential for the survival of terrestrial ecosystems.

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

Ecological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Survival rate of honeybee (Apis mellifera) workers after exposure to sublethal concentrations of imidacloprid

, 2010
Imidacloprid is a commonly used systemic insecticide which can induce several sublethal effects. Previous research has not shown any increased mortality in bees that were fed with sublethal doses. However, there is very little research conducted with the

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

Ecological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Parasit-Wirtsbeziehungen zwischen Varroa destructor Anderson und Trueman und Apis mellifera L.

, 2005
Life of Varroa destructor, Anderson and Trueman, an ectoparasitic mite of honeybees, is divided into a reproductive phase in the bee brood and a phoretic phase during which the mite is attached to the adult bee.

Polyadenylation of ribosomal RNA in response to picornavirus infection in honey bees (Apis mellifera) [PDF]

, 2012
At least eighteen different picornaviruses can infect honey bees (Apis mellifera). The combination of the virulence of these pathogens as well as their transmissibility through Varroa destructor, an ectoparasitic mite, can cause severe declines in honey ...
