In 2006, bees across the U.S. started dying rapidly. Now, the U.S. honey bee population is at an all-time high, according to the Census of Agriculture. Clay Bolt, manager of pollinator conservation for the World Wildlife Fund U.S., joins CBS News to explain what happened.May 14, 20...
Apis mellifera scutellata(the African savannah honey bee) is known for being defensive, having a high swarming rate, being migratory, and possessing other phenotypes many beekeepers view negatively9,18,19. This is the bee that was introduced into Brazil in 195720,21and later became known as the...
Honey beeApis melliferstored pollen grainsbrood activityThe present work was carried out to study the relationship between brood rearing activity, bee density and stored pollen grains. Fifteen colonies, 1st. Carniolan hybrid nearly in equal strength were put under investigation from June 1994 to May...

The genetic diversity within each bee colony, particularly as a consequence of polyandry by queens, may enable preservation of genetic diversity even during population bottlenecks. These findings suggest that genetically diverse honey bee populations can recover from introduced diseases by evolving rapid ...

Varroa destructor is the main culprit for the death and reduced populations of overwintered honey bee (Apis mellifera) colonies in Ontario, Canada The relative effect of parasite levels, bee population size, and food reserves on winter mortality and post winter populations of honey bee colonies was...
If you also take on the bee's role, you will be able to speed up the growth of your bee population, which will result in a larger honey harvest. You may begin the Adventure game and have some fun with the bees by touching or clicking on the bee. Your objective is to guide the be...
A honey bee colony contains a high density of visually similar members, rapidly moving and occluding on the uneven and changing honeycomb surface, and whose numbers change in time. These factors present substantial difficulties for automated image analysis9,10,11for which a common solution is to ...
Here, we performed a pan-European assessment of the virosphere of 12 bee communities, each consisting of three bee groups: bumble bees, solitary bee species and sympatric managed honey bees, on a continental scale and across different climatic zones (Fig.1). Using an AICc-based multi-model in...
