Abstract
The present work was carried out for studying, the activity of honey bee colonies in gathering pollen grains and Investigate the effect of bee venom (via scheduled bee stings) on the progression of chronic viral hepatitis B & C in Egyptian patients. Data revealed that, the average weight of trapped pollen pellets collected throughout the year was 1786.11 gm. /colony,. There were 24 sources from which honey bee workers collected pollen grains all- over the year. The quantities of trapped pollen pellets during the year could be arranged descendingly as follows, Maize (17.17%),Clover (12.92%), Coriander (11.19%), Pick tooth (11.09%), Citrus (8.84%), Elephant grass (8.49%), Wild mustard (7.43%), Date palms (6.16%), Rocket (3.68%), Crown daisy (3.19%), Sorghum (0.93%), Castor oil (0.68%), Marjoram (0.50%), Eucalyptus (0.42%), Casuarina (0.22%), Sesame (0.22%), Pumpkim (0.21%) and Jute mallow (0.04%) The 6 unidentified sources represented 6.59% of the quantity of collected pollen pellets all- over the year. The average weight of trapped pollen pellets during spring was 820.09.gm. /colony representing 45.91% of the total quantity of trapped pollen all-over the year. There were 9 sources from which honey bee workers collected pollen grains during spring . Colver (Trifolium alexandriunm,) was the most important representing 28.14%) The average weight of trapped pollen pellets for summer was 317.51 gm. /colony representing 17.87 % There were 6 sources of pollen grains. : Maize (Zea maize,) was the most important representing. 69.53% The average weight of trapped pollen pellets during autumn was 84.67gm. /colony, representing 4.74 %.There were 9 sources of pollen grains: Maize (Zea maize,) was the most important representing.., 67.71% % . The average weight of trapped pollen pellets during winter was 563.75gm., representing 31.56%. There were 13 sources of pollen grains: Citrus (Citrus spp,) was the most important representing..,. 26.03%), Date palms (Phoenix dactylifera ), representing. 18.95%,
