Activity level of lactate dehydrogenase and β-glucosidase enzymes in the honeybee colonies, (Apis mellifera L.) with different feeding

Article History The activity of Lactate dehydrogenase and β-glucosidase was determined in Carniolan workers honey bee, Apis mellifera L. after feeding on different diets antibiotic ,ripe milk and some natural plant extract (thyme, clove, cinnamon, black seeds and anise) . The results showed the highest increase in the β-glucosidase activity was occurred in the diet containing Ripe milk (106.17%) and the other diets scored decrease in the activity , as well as the Lactate dehydrogenase activity the results showed highly enzyme activity in diets antibiotic and clove 192.56%, & 215.70%. respectively as compared with the other diets used in this study.
