Abstract
The drones are the males of the honeybee, produced from unifertilized eggs, and reared in cells larger than those used for rearing workers. The drone larvae grow larger and during their development receive considerably more food than do the worker larvae. According to Stabe (1930) the maximal weight attained by the drone larvae is 384.0 mg. as compared with 159.1 mg. for worker larvae. Planta (1888) weighed the food of larvae from drone cells and found an average of 9.6 mg. of food per cell, while there was only 1.7 mg. of food per worker cell. Values given by Aeppler (1922) correspond quite closely to those of Planta. Planta (1888) also called attention to the fact that the food of drone larvae more than 4 days old contained large amounts of pollen grains (15,000 pollen grains per mg.) while the food of worker larvae of the same age was almost pollen-free. The food of both worker and drone larvae under 4 days old was pollen free.
