Electron microscopic studies on the follicle epithelial cell—oocyte cortex interface inArrhenothrips ramakrishnae Hood (Insecta: Thysanoptera)

Abstract

Observations relating to nuclear and perinuclear-cytoplasmic changes in the follicular epithelial cells as well as changes at the follicle epithelial cell-oocyte cortex interface in Arrhenothrips ramakrishnae Hood, based on transmission electron microscopy are presented. The significance of increased pinocytosis during the later stages of the growth phase of follicle epithelial cells, the appearance of refractile bodies, as well as the apposition of numerous mitochondria of varied configuration to the rough endoplasmic reticulum are discussed.
