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.
