Controlled Mating and Hygienic Behaviour

we compared the levels of hygiene in colonies headed by daughter queens reared from hygienic mother colonies that were either instrumentally inseminated with sperm from drones reared from hygienic colonies or allowed to mate naturally with naturally-occurring drones.

Genetic Origin & Survival

On average, colonies with queens from local origin survived 83 days longer compared to non-local origins (p < 0.001). This result demonstrates strong genotype by environment interactions. Consequently, the conservation of bee diversity and the support of local breeding activities must be prioritised in order to prevent colony losses, to optimize a sustainable productivity and to enable a continuous adaptation to environmental changes.

Bacteria Help Honey Bee Larvae

grafting queen rearing larve

Honey bees are under constant pressure from a whole host of stresses—diseases, poor nutrition,sublethal effects of pesticides, and many others. While researchers have been aware for a number of years of a community of bacteria in adult bees that may aid with some of these stresses,Agricultural Research Service researchers have identified the first bacteria that…

Local bees better than imports

locally adapted strains of honey bee consistently performed better than the “foreign” strains. Honey bee genotypes and the environment In recent years, much attention has been focused on the global problem of honey bee colony losses. Among the many explanations for these losses, variability in the genetic makeup and vitality of honey bee populations

Male Fitness of Honeybee Colonies

We found clear evidence for an extensive diversity in
male mating success at the colony level. Some colonies
had significantly more matings (about an order of
magnitude) than other drone producing colonies in the
same year.
