摘要

姬蜂(膜翅目:Ichneumonidae)是蜘蛛的体外寄生虫,通过诱导蜘蛛网的变化来改变寄主的行为。雄性生殖道的变化有助于加深我们对这些昆虫生殖行为的了解。本研究利用光学显微镜描述了双色姬蛙(Hymenoepimecis bicolor,Brullé,1846 年)雄性生殖道的形态。H. bicolor 的雄性生殖道由一对睾丸组成,每个睾丸包含一个卵泡、两个输精管、一个射精管和两个附属腺体。睾丸卵泡在精子发生的不同阶段都有囊肿,表明精细胞正在发育和成熟。输精管细长,远端盘绕,近端与一对附属腺体侧向相连。输精管壁有简单的立方体上皮。附属腺体有简单的柱状上皮,腔内充满异质内容物。没有精囊。H. bicolor雄性生殖道的解剖学和组织学与其他膜翅目昆虫相似,这表明寄生虫的行为不会导致其生殖器官发生重大改变,说明膜翅目昆虫的生殖道是保留的,与它们的行为无关。

Anatomy and histology of the male reproductive tract of the parasitoid wasp Hymenoepimecis bicolor (Brullé, 1846) (Hymenoptera: Ichneumonidae)
Hymenoepimecis wasps (Hymenoptera: Ichneumonidae) are ectoparasitoids of spiders that modify the hosts’ behaviour by inducing changes in webs. Variations in the male reproductive tract contribute to enhancing our understanding of the reproductive behaviour of these insects. This study describes the morphology of the male reproductive tract of Hymenoepimecis bicolor (Brullé, 1846) using light microscope. The male reproductive tract of H. bicolor consists of a pair of testes, each containing a single follicle, two vasa deferentia, one ejaculatory duct and two accessory glands. The testis follicle has cysts at various stages of spermatogenesis, indicating ongoing sperm cell development and maturation. The vasa deferentia are elongated, with a coiled distal portion, whereas the proximal regions are laterally associated with a pair of accessory glands. The wall of the vasa deferentia has simple cuboidal epithelium. The accessory glands had a simple columnar epithelium with the lumen filled with heterogeneous content. The seminal vesicle is absent. The similarity in the anatomy and histology of the male reproductive tract of H. bicolor with other Hymenoptera suggests that the parasitoid behaviour does not result in significant alteration to their reproductive organs, indicating that the reproductive tract is conserved in Hymenoptera, regardless of their behaviours.

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.
