Foraging and hoarding efficiency in Buckfast purebreds and Norwegian Black Bee (A. m. mellifera) hybrids.Part 2. Comparison with the Caucasian bee hybrids under flying cage and laboratory test conditions

Three genetically different bee groups: Buckfast (Bcf), crossbreeds derived from mating Norwegian queens (A. mellifera mellifera) with Caucasian drones (Nor x Cau) and hybrids derived from mating Caucasian queens with Carniolan drones (Cau x Car) were compared for their ability to forage and store sugar food in field tests under flying cages and in laboratory tests. Cau x Car were used as reference/background for the former two groups. In the field trial, Cau x Car foraged the greatest amount of syrup followed by Bcf and Nor x Cau. The same results were obtained when the collection of candy by caged bees was evaluated in the laboratory. The amount of syrup foraged by bees bore no relationship to its amounts hoarded in the combs nor to the amount of candy collected in the laboratory. The greatest amount of supplies were hoarded by Bcf to be followed by Cau x Car and Nor x Cau. It was because Bcf processed the greatest amount of foraged syrup into stores and Nor x Cau were superior to Cau x Car, the latter being the worst performing sugar syrup hoarders. Bcf bees can be recommended for use and their performance can be due, to a large extent, to their general combining ability. In Norwegian bees specific combining ability can be a factor of much importance.
