Abstract
This work was carried out in the apiary of Agric. Fac. Cairo Univ., Giza, Egypt during spring and summer seasons of 2015 to study the spatial distribution of young and old honeybee drones Apis mellifera L.. The obtained results showed that the spatial distribution of drones was differed according to their ages and seasons of the year. Generally the immature adult drones tend to concentrate on the brood combs, whereas the mature ones were showed on peripheral combs. On the other hand during the cold months the majority of young drones were showed on the central combs, whereas the stable temperature which was suitable for their sexual maturity.
Highlights
It is well known that the brood combs (combs contained eggs, larvae and pupae) are occupying the middle area of honeybee brood nest, while the stores, (pollen and honey), occupying the peripheral combs of it, (Free & Williams, 1975)

Spatial distribution of immature drones: Data presented in Table (1) and illustrated in Figures (1, 2 and 3) showed the distribution percentages of young and old honeybee drones on the colony combs throughout March, April and May, 2015
Summary
It is well known that the brood combs (combs contained eggs, larvae and pupae) are occupying the middle area of honeybee brood nest, while the stores, (pollen and honey), occupying the peripheral combs of it, (Free & Williams, 1975). The inspection operation was done by one investigator in the morning, (between 8.00 -9.50 a.m. during spring and 7.50 - 9.00 a.m. during summer), before drone flying time, where the marked drones on each comb were counted. The percentages of the recorded numbers of drones on each comb for each tested colony during spring and summer seasons were calculated and take in consideration in the presentation and discussion of the results.
