Breeding for hygienic behaviour in honeybees (Apis mellifera) using free-mated nucleus colonies

Determination of change in hygienic behaviour in a selected population without controlled mating Table I gives the median values of THB and PHB for the whole population

The lack of sig- nificant variation in the infestation levels in the brood could have resulted from the lack of differences between groups for hygienic behavior, brood attractiveness

Abstract – Sudanese honeybee populations are surrounded by a suite of various subspecies with di fferent mitochondrial haplotypes, including the O-lineage in the north (Egypt),

In this study, we confirmed that Apis mellifera scutellata bees are able to remove introduced mites and recap the brood cells; therefore, Varroa - specific hygienic behavior

Mean (± SE) percentage removal of dead European honey bee adults from within control and thymol-treated hives prior to thymol treatment (assay 1) and during thymol treatment (assays

The migration dances differed from wag- gle dances observed during the swarming peri- ods and exhibited many of the same character- istics previously described for tropical honey

The basic idea of the two methods is to sacrifice a determined area of sealed brood in the hive and to record how much the worker bees clean that area by removing dead larvae from it

When the worker cells on the experimental frames were sealed (day 9) in the eight queenless subunits (1B –8B), queens with a yellow cuticle (yellow queens; A. ligustica )
