Abstract: The effect of varroosis infestation rate on morphometric indicators of wild bees living in natural conditions in the mountain-forest zone of the Republic of Bashkortostan was studied. There were no significant differences in the wing size while the high infestation rate of bee colonies with Varroa destructor (22-24 %) resulted in smaller proboscis length by 12%. Significant differences were also, found for mean values of the length and the width of the 3rd abdomen sternite of worker bees from the colonies with varying degrees of infestation (p>0.001) and the length and the width of the wax mirror. No significant dissimilarities in the size of the 3rd tergite and the cubic index were found. The measurement of the fat body cells characteristics by the method of Tuktarov and Ishmeeva showed that the size of both fat cells and bees oenocytes for the colonies with higher infestation rate was significantly less (p>0.001) than that for the bees from lower infested colonies.
