The ultrastructure of the anal vesicle of the parasitoid, Microplitis croceipes (Hymenoptera:Braconidae).


:The fine structural characteristics of epithelial cells of the anal vesicle in the hymenopteran parasitoid, Microplitis croceipes (Cresson), are similar to those of transport cells. Apical and basal infoldings, an abundance of mitochondria, ribosomes, rough endoplasmic reticulum, Golgi complexes and pinocytotic vesicles all indicate a transport function for these epithelial cells. The medial portions of both Malpighian tubules located within the anal vesicle also were examined and on the basis of morphology appear to be active. These observations support earlier physiological data which indicate that the anal vesicle functions in absorption of nutrients and excretion.
