Characteristics of Apis cerana (hymenoptera: apidae) and effects of diet variability on bee venom quality and quantity in Peninsular Malaysia

The bee venom is a complicated chemical and pharmacological product, which has been used for healing several diseases for many centuries by different nations. The components of venom, especially melittin, phospholipase A2 and apamin are the main qualitative factors that affect its chemical propertie...

Whereas, the quantity analysis resulted high weight of 7.65±0.25 μg was achieved by star fruit. The effect of carbohydrate and protein rich mixture was studied. The results showed that the venom produced by bees foraged on supplementedcarbohydrate diets, had melittin, phospholipase A2 and apamin of 535.21±17.73, 374.49±18.94 and 130.36±12.05 μg/μl respectively. The comparison of the alternative diets proved that the protein rich mixture is better than both sucrose diet and the natural diet for yielding venom with high quality. Relocation of the hives from their original locations to the area with different flora led to obvious changes in the quality and quantity of the bee venom. The results showed that the most significant difference was observed in the concentration of the phospholipase A2 between pink power (420.85±13.15μg/μl) and star fruit (360.41±15.74μg/μl).
