| 摘 要： | 为了解茶树主要食叶类害虫灰茶尺蠖(EctropisgrisescensWarren)雌成虫的内外生殖器结构特征,通过解剖切片和显微观察的方法,明确了雌成虫内外生殖器主要由1对卵巢、1对侧输卵管、1根中输卵管、1个受精囊、附腺、产卵孔、交配囊及其附属结构、导精管、表皮突和肛突等组成。卵巢小管8根,左右对称;交配囊呈典型袋状结构,内有表面布满刺状突的心型交尾囊片,且囊片左右两侧16根刺状突呈对称分布;后表皮突较细长,似铲状。切片观察可知,卵巢管滋养细胞和卵母细胞交替排列,为典型的多滋式;产卵器内有发达的性腺等。掌握灰茶尺蠖雌成虫生殖器结构,对其卵巢发育级别划分、田间预测预报、近缘种的鉴定以及性信息素的研究等具有重要意义。

| Abstract: | The tea geometrid, Ectropis grisescens Warren is a major defoliator of tea trees. The morphology and histology of internal and external reproductive organs of the female adult insects were described here using both anatomical sections and microscopic observation. The female adult reproductive organs were comprised of a pair of ovaries, two lateral oviducts, one common oviduct, spermatheca, accessory gland, oviporus, corpus bursae and associated parts, ductus seminalis, apophyses and papillae anales. Each ovary contained eight symmetrical ovarioles. The corpus bursae was a typical bag structure and possessed a heart-shaped signum which covered 16 symmetrical spines on the surface of both sides. The apophyses posteriores was slender and shovel-like. Nurse cells and oocytes were arranged alternately in polytrophic ovarioles. The ovipositor possessed a well-developed gonad. This study was the first research on the genital structure of female adult of E. grisescens Warren. The results provided guidance for the study of ovarian development, field forecasting, and identification of related species. |
