Abstract :

The female reproductive morphology and histology of Graphosoma lineatum (Heteroptera: Pentatomidae) was examined by light and scanning electron microscopy. We found that the female had a pair of ovaries, each with 7 meroistic telotrophic ovarioles, a pair of lateral oviducts, a common oviduct, a spermatheca, accessory glands and a genital chamber. Each ovariole is composed of four main regions: (1) the thread-like terminal filament (2) the tropharium, a chamber housing anteriorly the nurse cells and posteriorly the young oocytes, (3) a long vitellarium composed of a series of oocytes, which become progressively large towards the posterior and, and (4) the pedicel (ovariolar stalk) in which the mature eggs are lodged before passing into the lateral oviduct.
