The effect of feeding honey bee colonies on a sugar solution to which bee venom has been added at a concentration of 50 mg/liter sugar solution and on amino acids extracted from clover 4 cm amino acids/liter sugar solution on the amount of food consumed by honey bee workers as well as the effect on gland tissues Hypopharyngeal and maxillary glands and histological changes that occur in them. Nine honeybee colonies were tested in an apiary of the Bee Research Department, Plant Protection Research Institute, Agricultural Research Center, Ministry of Agriculture, Giza, Egypt, during 2020-2021. Statistically, there are no significant differences in the amount of food consumed by honeybee workers, whether the bee venom solution or the amino acid solution, compared to the control colonies that fed on the sugar solution only. No histological changes were observed in the hypopharyngeal (HPGs) and mandibular glands (MGs) in workers fed sugary solution (control colonies). Feeding with amino acids resulted in histological changes in the HPGs and MGs, as most of the acini were atrophic and smaller in size than usual, with the loss of vesicles in the cytoplasm. As for the bees that fed on a solution of bee venom, histological changes in the HPGs and MGs were observed, where severe atrophy and contraction of the acini with an irregular outline were noted. Nuclear thickening of the epithelial cell lining was observed. The histological structure of the lower glands showed atrophy in some individual cells, which led to damage to the development of both the HPGs and MGs.
