The drone brain structure of Apis cerana cerana was observed by histological  technique. The results indicated that the brain structure is composed of protocerebrum, deutocerebrum and tritocerebrum. The mushroom bodies of drone are smaller thanthose of worker bee and queen bee,  center body of drone is smaller than that of worker bee, similar to the queen bee. There is big olfactory lobe in deutocerebrum, which indicated that drone has well developed olfactory system, then this makes them in the mating process with the queen bee can be more sensitive receiver from the queen bee of the sex pheromone, but macroglomerular complex is underdeveloped.
