Abstract
The spatial distribution of worker honeybees in colonies of two African sub species (Apis mellifer a capensis and Apis mellifera scutellata), as well a s their natural hybrids, was determined in five observation colonies, each containing one frame. The queens were allowed to roam freely throughout the hive during the initial phase of the experiment, and were observed on both sides of the frame in all colonies. In the second phase of the experiment the queen was caged on one side of the frame in three of the observation co lonies, the other two colonies serving as controls. Queen caging significan tly affected the distribution of worker bees, with more A. nz. scutellata w orkers being attracted to the queen and more A. m. capensis worker bees bei ng repelled by the presence of the queen. The hybrid workers were also repe lled, but to a lesser extent. Queens thus not only attract workers to form a retinue or during swarming but also repel workers in the nest. Evasion of the reproductive suppression by the queen pheromones may be a typical beha vior for workers with a high reproductive potential.
