摘要
本文详细研究了大草蛉雌性生殖系统的解剖学和组织学特征，以及各部分的功能。
The ovarioles of the female reproductive system of Chrysopa septempunclata Wesmael are of the polytrophic type. There is one oocyte and 8 nurse cells in each follicle. A well developed ovariole consists of terminal filament, gemarium, previtellarium, vitellarium and pedicel. According to the changes of oocytes, nurse cells and follicular cells in the ovariole,the process of oogenesis can be divided into ten successive stages, five for the previtellarium ,and five for the vitellarum. Histologically, the lateral oviduct, median oviduct and vagina obviously differ in epithelial sizes, arrangements of muscles and intimas. The epithelium of bursa copulatrix is thin, but its intima is thicker with two layers. The muscles around the bursa copulatrix are arranged disorderly. The spermatheca is lined with a strongly sclerotized intima. The spermathecal duct can be divided into two parts, and the colleterial and scent glands are different, histologically. The function of every part of the female reproductive system of Chrysope septemponctata Wesmael is also analysed and discussed.
