| Abstract | ||||
| The present work aimed to study the relation ship between brood rearing and stored pollen in trapped colonies (colonies with pollen traps) and non trapped colonies (colonies without pollen traps). The highest average of worker brood in trapped and non trapped colonies were observed in summer, while the lowest average was in autumn. Areas of worker brood differed significantly and were high in summer and spring season according density of bees in trapped and non trapped colonies. Highest amount of stored pollen was observed during Spring and Summer season, represented (670 sq .in (36%) and (826 sq .in (45%) in trapped colonies , while that was (768 sq .in (27% ) and (1135 sq .in (40% ) in non trapped colonies , respectively . Highest rate of stored pollen and brood rearing recorded in spring and summer seasons. The Lowest amounts of stored pollen and brood was observed in autumn and winter. Non trapped colonies reached to 428 sq .in (15%) and 519 sq .in (18%), respectively, while trapped colonies were 149 sq .in (8%) and 203 sq .in (11%) of stored pollen with brood 457 sq .in (12.36%) and 188 sq .in (5.08%), respectively. Non trapped colonies collect more pollen and rear more brood than trapped colonies. The amounts of stored pollen and the rearing sealed brood can arranged in a descending order from summer, spring, autumn and winter. | ||||
