摘要

我们利用光显微镜和扫描电子显微镜技术研究了具有重要经济价值的柞树雌性生殖系统的形态。蟋蟀(Cercopis vulnerata)的雌性生殖系统有两个卵巢,每个卵巢包含 14 个远养型子房卵泡,由两个侧输卵管连接,侧输卵管开口于一个共同的输卵管。在这种卵巢中,胚芽室内的滋养细胞通过营养索转移到玻璃体内发育中的卵母细胞。卵黄室内的卵母细胞有三个不同的发育阶段:前卵母细胞、卵黄细胞和绒毛膜形成期。卵裂打开在侧输卵管中,侧输卵管的梗呈细管状。一对侧输卵管上部开口于总输卵管。输卵管周围是单层立方上皮,向管腔方向有深皱褶,并有厚厚的肌肉层。在总输卵管附近可以看到一对精囊和一个交配囊。精囊呈细长形。交配囊呈卵圆形管状结构。迄今为止,还没有关于栉水母科雌性生殖系统的研究。本研究旨在填补这一空白,并构成这种具有重要经济价值的昆虫的雌性生殖系统形态学的一部分。

Notes on the female reproductive system of the red-and-black froghopper, Cercopis vulnerata Rossi, 1807 (Hemiptera: Cercopidae)-light and electron microscopy studies

The morphology of the female reproductive system in Cercopis vulnerata, an economically important species, was examined with light and scanning electron microscopy techniques. The female reproductive system of C. vulnerata has two ovaries, each containing 14 telotrophic meroistic ovarioles joined by two lateral oviducts that open in a common oviduct. In this type of ovarioles, the trophocytes within the germarium are transferred to the developing oocytes in the vitellarium via the nutritive cords. The oocytes in the vitellarium have three different development stages: previtello, vitello and choriogenesis. The ovarioles open in the lateral oviduct with a thin canal-shaped pedicel. A pair of lateral oviducts opens distally into the common oviduct. The oviducts are surrounded by a monolayer cubical epithelium with deep folds toward the lumen and a thick muscle layer. A pair of spermatheca and a bursa copulatrix are seen near the common oviduct. Spermatheca has an elongated shape. The bursa copulatrix has an ovoid tube-like structure. No work has been done on the female reproductive system of Cercopidae to date. This study was conducted to fill this gap and forms part of the female reproductive system morphology of this economically important insect.

期刊介绍: Published regularly since 1920, Acta Zoologica has retained its position as one of the world''s leading journals in the field of animal organization, development, structure and function. Each issue publishes original research of interest to zoologists and physiologists worldwide, in the field of animal structure (from the cellular to the organismic level) and development with emphasis on functional, comparative and phylogenetic aspects. Occasional review articles are also published, as well as book reviews.
