Abstract
This study carried out to measure amounts of stored pollen during two bee activity season (spring and summer) under effect of some climatic factors (Temperature oC, relative humidity % and photoperiods). The results showed that, it found relationship between amounts of stored pollen and degrees of these climatic factors. Large amounts of stored pollen were recorded in July and August, reached to 910 and 934 sq.in/colony, respectively. less amounts of stored pollen were noticed in March and April, reached to 375 and 414 sq.in /colony, respectively . High rate of stored pollen were recorded in summer season (2554 sq.in/colony) under temperature 28.5oC, relative humidity 62.37% and photoperiod 13:5 hour. There were found high significant differences between amounts of stored pollen in July and both March and April. While it was found insignificant differences between amounts of stored pollen in spring and summer months
