Abstract  

Two geographical subspecies of the honeybee Apis mellifera, the European bee A. m. carnica and the Egyptian bee A. m. lamarckii, were investigated by direct calorimetry. Maximum, mean and minimum heat production rates were determined for groups of 6 bees as a function of temperature and daytime. Smaller Egyptian subspecies showed significantly higher mass specific metabolic rates than the European one. Maximum and mean heat production rates decreased exponentially with growing temperatures while the minimum values remained constant.
