中文摘要：沙棘木蠹蛾Holcocerus hippophaecolus Hua，Chou，Fang et Chen 属鳞翅目( Lepidoptera ) 木蠹蛾Cossidae)，是我国的特有种。2001 年以来，沙棘木蠹蛾在我国大面积爆发，是屹今为止我国沙棘林最大的蛀干害虫，给我国的沙棘产业造成了巨大的损失。本论文从形态学和组织学2 个方面确定了沙棘木蠹蛾雌、雄生殖系统的特征，同时，对比了雄性交尾前后生殖系统各部位的差异。未交尾雄蛾的生殖系统贮精囊、附腺管和射精管呈白色，其内包含大量的精子束待交尾，已交尾雄蛾的生殖系统呈透明或半透明状。除雄性附腺外，在交尾后的精巢、贮精囊和射精管中都能观察到真核精子束。通过上述对雄性生殖系统的形态学和组织学观察，尤其是对贮精囊和射精管中精子束观察，可判断精子束的填充状态，从而判断雄蛾交尾与否，能够检验性信息素引诱剂对沙棘木蠹蛾的防治效果，确立判断雄蛾交尾与否的标准对指导沙棘木蠹蛾防治具有重要意义。
英文摘要：Holcocerus hippophaecolus Hua，Chou，Fang et Chen ( Lepidoptera，Cossidae) is endemic to China and a
serious pest of seabuckthorn forest that has caused tremendous losses． Large-scale outbreaks of this pest have beenreported since 2001． This paper describes morphological and histological characteristics of the male and femalereproductive system of H． hipophaecolus and differences in the male reproductive system before and after mating． Inunmated males，the seminal vesicles，accessory glands and ejaculatory ducts are white and contain a large number ofsperm bundles． However，in males that have mated，the reproductive system is transparent and translucent． Spermbundles can be observed in the testis，seminal vesicles and ejaculatory ducts in addition to the accessory glands． Thisobservation，and especially the distribution of sperm bundles，can be used to distinguish between mated and unmatedmales． The ability to distinguish these is useful for evaluating the efficiency of sex pheromone traps．
