Variability of Filling and Changing of Honey Crop Microstructureof Bee Apis mellifera L.
The dependence of crop filling on the physiological state of bees and the quality of carbohydrate feed has been established. Semi permeable walls of crop provide regulation of water content in carbohydrate feed. The crop wall is formed by the muscular layer, under which the mucous membrane is located. The elongated cells forming it extend as they fill the crop, along the muscle layer. Poisoning bees with lead or cadmium generates irreversible degenerative-dystrophic and necro-biotic changes in the crop wall.
