Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Agriculture - Department of Economic Entomology and Pesticides Summary: The highest mean values of sealed drone and worker brood throughout 2012 were 104.0 in2/colony & 521.8 in2/colony induced in May. No drone brood was produced in November and the lowest mean value of worker brood was in January with value 108.8 in2/colony. Also, the highest & lowest mean values of stored pollen occurred in August & March with values 300.3 in2/colony & 32.3 in2/colony, respectively. Moreover, the highest rate of construction queen cups and queen cells was occurred in spring with mean values of 14.3 queen cup/colony & 4.2 queen cell/colony, respectively. Superiority of Carniolan hybrid in drone brood production compared with Italian hybrid, with means 8.8 in²/colony & 6.4 in²/colony for both hybrids, respectively. Also, Carniolan hybrid had superiority and significantly higher than Italian one in weight of drones with means 201.7mg/drone & 194.6mg/drone for both hybrids, respectively. Also, pollen made a positive effect by increasing rate of drone brood rearing, colonies without pollen traps reared drone brood with a general mean 13.1 in2/colony compared with 8.0 in2/colony for colonies with traps. Also, pollen traps caused a drone brood reduction ranged from 45.9% (in spring) to 50.0% (in summer), in addition colonies without pollen traps had increasing in drone weight reached 231.3mg/drone compared with 217.4mg/drone for colonies with traps. The mean values of drone brood reared were 3.3 in2/colony & 6.1 in²/colony for the young & old queens, respectively. Furthermore, the supplemental feeding consists of chickpea plus yeast was considered the best one compared with soybean plus yeast and sugar syrup only in both of drone brood rearing & weight of newly emerged drones, with means 10.2 in²/colony, 5.5 in2/colony & 4.4 in2/colony for the three supplemental treatments, respectively. Also, in drone weight; 238.8mg/drone , 236.7mg/drone and 226.3mg/drone, respectively
