Abstract

The ultrastructure changes in the ovarian follicle of normal adult females and those developed from treated 5th nymphal instar of Schistocerca gregaria with LC50 of anti-chitin compound (cascade), plant extract (Orizasativabranextract)and synthetic pyrethroid (Karate) were examined.
In the present study electron micrographs of follicle cells of treated adult females with previous compounds showed a degeneration of ovarioles and oocytes .There is also evidence of mitochondrial disintegration . It is also noticed that  vacuoles were increased and enlarged in follicle cells and yolk bodies were cracked mostly in two halves.
