Summary The changes in the ultrastructure of the oöcyte and associated follicle cells during oösorption in Locusta migratoria migratoroides are described. Throughout the process the follicle cells act in a phagocytic manner and invade the oöplasm. Localizatio of acid phosphatase activity indicates that at the start of resorption the Golgi complexes of the follicle cells begin to produce lysosomes on a large scale, and that these are utilised in the breakdown of yolk spheres which have been taken up from the oöcyte. Partly degraded yolk spheres are collected together along with other cell organelles into cytolysomes. The significance of large numbers of microtubules within the follicle cells and of microvillar borders between the cells in late stage resorbing bodies is discussed.
