The Common Types of Pollen Grains Collected by Honey Bee Workers Apis Mellifera, L. (Hymenoptera:Apidae) in El-Sabheia Region, Alexandria Governorate, Egypt

Abstract

pollen grains are major source of protein, fats, vitamins and minerals. It is essential for the growth of larvae and young adult bees. Collecting pollen depend on many factors such as race of honey bee, honey bee health, environmental conditions and planting area around the apiaries. The present study is concerned with the effect of pollen grains type, effect of using pollen trap on honey produce, brood production and trapped pollen. The obtained results showed that the highest amount of trapped pollen was in August and summer season, while the lowest amount was in May and spring season, also in September there were the highest mean areas of sealed brood and honey at the colonies of traps and without trap while the lowest mean was in May in colonies with traps and without traps. Also results revealed that there were 5 different floral sources were Phragmites ustralis, Eucalyptus, Calistemon visiminalis, Schinus terebinthifolius and Trifolium alexandrinum. Chemical analysis of the trapped pollen grains showed that pollen of Calistemon viminalis recorded the highest level of moisture, crude protein, ash and crude lipids, while Eucalyptus pollen grains recorded the highest amount of reducing sugar and the lowest amount of crude protein
