摘 要:山核桃透翅蛾Sphecodoptera sheni是薄壳山核桃Carya illinoensis的一种主要蛀干害虫,为明确其成虫生殖系统的结构,利用光学显微镜和扫描电子显微镜观察解剖后的雌雄成虫生殖系统的形态和结构。结果表明:山核桃透翅蛾的内生殖器在蛹期就已基本完成发育。雄蛾内生殖器由精巢、贮精囊、输精管、复射精管、单射精管和附腺组成;雌蛾内生殖器包括卵巢、侧输卵管、中输卵管、生殖腔、受精囊和附腺。雄蛾外生殖器包括抱握器、背兜、基腹弧、囊形突、爪形突和阳茎等结构;雌蛾外生殖器主要由交配囊及其附属结构、导精管、前表皮突、后表皮突、肛突组成。本研究结果不仅丰富了山核桃透翅蛾的形态学分类特征,也为其生殖生理学研究提供理论基础。Sphecodoptera sheni is the major trunk borer of Carya illinoensis.To clarify the structure of the reproductive system of S.sheni adult,the morphology and structure of the dissected reproductive system of S.sheni adults were observed by optical microscope and scanning electron microscope.The results indicated that the internal genitalia development had been basically completed in the pupal stage.The internal genitalia of male S.sheni consisted of testes,seminal vesicles,vas deferens,ductus ejaculatorious duplex,ductus ejaculatory simplex and accessory glands;the internal genitalia of female S.sheni included ovary,lateral oviduct,common oviduct,genital chamber,spermatheca and accessory gland.The external genitalia of male S.sheni structure included such as harpes,tegumen,vinculum,saccus,uncus and aedeagus;the external genitalia of female S.sheni were mainly composed of bursa copulatrix and its accessory,ductus seminalis,anterior apophysis,posterior apophysis and papillae anales.The results not only enriched the morphological taxonomic characteristics of S.sheni,but also provided theoretical basis for the study of reproductive physiology of S.sheni.
