摘要

研究了眼刺虫雌性生殖系统的一般组织,阐明了受精囊和受精囊腺的复杂结构。这两个结构紧密地粘附在一起,共用一小块表皮上皮。一根长长的导管将交配囊与精子储存的受精囊连接起来。精子通过受精管到达卵子受精的共同输卵管。受精囊腺细胞有细胞外贮液池,贮液池中储存着分泌物。由导管形成细胞组成的细导管将这些分泌物输送到顶端腺区域并进入受精囊腔。交配后不久,交配囊几乎完全被雄性附属腺分泌的塞子占据。法氏囊上皮的分泌物似乎有助于栓塞的形成。后来,这个塞子变得又大又球形,阻塞了交配囊。

Fine structure of the female genital system of diving beetle Stictonectes optatus (Seidlitz, 1887) (Dytiscidae-Hydroporinae) and evidence of mating plug formation

The general organization of the female genital system of the diving beetle Stictonectes optatus was studied, clarifying the complex structure of the spermatheca and spermathecal gland. The two structures adhere closely to each other, sharing a small area of their cuticular epithelium. A long duct connects the bursa copulatrix to the spermatheca, where the sperm are stored. The sperm reach the common oviduct, where egg fertilization occurs, via a fertilization duct. The spermathecal gland cells have extracellular cisterns where secretions are stored. Thin ducts composed of duct-forming cells transport these secretions to the apical gland region and into the spermathecal lumen. Soon after mating, the bursa copulatrix is almost completely occupied by a plug secreted by the male accessory glands. The secretions of the bursa epithelium seem to contribute to plug formation. Later this plug becomes large and spherical, obstructing the bursa copulatrix.

期刊介绍: Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
