Copyright policy )Assortative mating in a mixed population of European Honeybees,Apis mellifera ligustica andApis mellifera carnica
The drone population at a natural drone congregation area (DCA) was composed of 50%Apis mellifera ligustica (L) and 50%Apis mellifera carnica (C) drones. Both kind of drones were monitored by frequent sampling. Significant differences in the vertical drone distribution were detected: at 4 meters the portion of L drones was larger and C drones were relatively more frequent in 20 meters. Virgin queens (L and C) were naturally mated in the DCA and mating frequencies for L and C drones were established. Their worker offspring was classified as pure Ls. pure Cs or hybrids. A significant tendency for assortative mating was found for both groups of queens. One of the mechanisms of mate choice may involve the differences in vertical distribution of the drones.
