Abstract
On the light of the obtained data, it could be concluded that activity of honeybee colonies for pollen collection under Qena conditions is controlled by many of factors which could be summarized in the following points:
1. The first hybrid Carniolan bee colonies recorded the highest annual rate of pollen collection, followed by colonies of the first hybrid Italian bees, while Egyptian bee colonies came in last.
2. Nag Hammady was the best location in Qena governorate for floral sources, followed by Nakada district, and then Armant district.
3. There is a positive correlation between both of number of the brood combs and population level of the honeybee colonies and their activity of pollen collection.
4. The suitable period for bees to collect pollen was that time of March, April, May, July, and August, however November, December, and January was the poorest time for availability of pollen sources.
5. Maize, Egyptian clover, faba bean were considered the main sources of pollen, while cauliflower, onion, and gourd were the minor sources of the pollen.
6.Chemical analysis and feeding test proved that pollen of Egyptian clover ,maize, and faba bean were the richest pollen of the most important components which support productivity of the bee colonies particularly in building their population and enhancement of brood, honey production.
