Abstract

In this study, we describe the features of oogenesis in the endoparasitoid, Pteromalus puparum, as well as the distinct type of programmed cell death of the nurse cells through conventional light and fluorescent markers for apoptosis and immunofluorescent analysis. Oogenesis in this endoparasitoid is divided into five stages, of which stages 1-2, 3-4, and 5 are corresponding to previtellogenic growth, yolk uptake, and the formation of egg envelopes, respectively. From these studies, we demonstrate two critical events, which are vitellogenin absorption and rapid transfer of nurse cell content, resulting in remarkable increase in the volume of oocytes during oogenesis in this endoparasitoid. Vitellogenin absorption initiates in the oocyte of early stage 3, and bulk transfer of nurse cell content into the oocyte occurs at stage 4 of oogenesis in P. puparum, which is mainly characterized with the programmed cell death in the nurse cell complex.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
