Abstract | ||||
Mid-gut of both early and late third larval instar of Gasterophilus intestinalis was investigated by electronmicroscop. Electronmicrographs of early and late larval instars illustrate difference in the structures of apical border, the microvilli, basal lamina, mitochondria and rough endoplasmic reticulum. Vacuoles of trilamellate layer bearing secretory granules are a characteristic feature of late instar. Also a lot of multivesicular bodies resulting from the degenerating of neighboring organelles. | ||||
