粉尘螨生殖系统形态学研究

粉尘螨Dermatophagoides farinae是一种重要的医学螨类。本文用光镜和扫描电镜研究了粉尘螨雌雄生殖系统的形态和结构。结果表明：雄性生殖系统由睾丸、输精管、 附腺、射精管、阳茎及附属交配器官组成。睾丸位于血腔末端，不成对,精原细胞、精母细胞和精子依照精子发育的顺序有规则地分布在其内部。雌性生殖系统包括交配孔、囊导管、储精囊、囊导管、卵巢、输卵管、子宫、产卵管及产卵孔，其中卵巢由一个中央营养细胞和围绕其周围的卵母细胞组成。

Morphological study of the reproductive system of Dermatophagoides farinae (Hughes) (Acariformes: Pyroglyphidae)

Dermatophagoides farinae is one of the important species of medical mite.In this study,the reproductive system of both male and female of D.farinae was investigated under both light and scanning electron microscopy.The results indicate that the male genital system consists of testis,vasa deferentia,accessory gland,ejaculatory duct,penis and accessory copulatory organs.Testis is situated in the haemolymphatic cavity of the opisthosoma and unpaired,in which spermatogonia,spermatocytes,spermatids and spermatozoa are regularly distributed in sequence during spermatogenesis.The female genital system consists of bursa copulatrix,ductus bursae,receptaculum seminis,ductus receptaculi,ovaries,oviducts,uterus,ovipositor and oviporus.Among them,ovaries are composed of a large nutritive central cell surrounded by germ cells of different developmental stages.
