Abstract
ACCESSORY nuclei have been described in the oocytes of Hymenoptera1–3 and some other insect orders. They are present during vitellogenesis, probably originating from the oocyte nucleus3. Structurally they resemble nuclei and their electron-dense inclusions contain RNA, possibly of nuclear origin. They seem to be concerned with the control of the synthesis of albuminous yolk and afterwards perhaps with the formation of the vitelline membrane3,4. In Nasonia vitripennis (Walk), they first appear near the nucleus of the oocyte, and spread from there through the peripheral cytoplasm (Fig. 1).
