| Abstract | ||||
| This study was conducted to measure the daily activity of collecting pollen during the activity seasons (spring and summer) under the influence of some climatic factors (Temperature oC, relative humidity % and photoperiods ). The results showed that, the highest quantities of pollen collected from 10 am to 12 pm (10 am -12 pm). In each of the spring and summer seasons with an average of 4.80 g / colony, the highest daily amount recorded during the month of May with a total average of 26.80 g / colony, while the lowest daily amount was recorded in August at 4.34 g / colony. There were insignificant difference between the amount of pollen collected in spring and summer during the period (8-10 am), (12-2 pm), (2-4 pm), (4-6 pm). While there were significant differences between the quantities of pollen collected in the period (10 am – 0.12 pm) in both spring and summer. Honey bees were more active in pollen collection (10 am – 12 am) and less active (4-6 pm) in both spring and summer seasons. | ||||
