Anatomy and ultrastructure of the female and male reproductive system in Acarus siro L. were investigated by light and electron microscopy. The female system consists of paired ovaries of nutrimentary type in which oogonia and oocytes are connected by bridges with a large central cell. The oviducts empty into the uterus, which passes into preoviporal duct lined by cuticle, and opening as a longitudinal slit (oviporus). An elongated accessory gland composed of one type of secretory cell is located along each oviduct. The copulatory opening occurs at the posterior margin of the body and leads, via the inseminatory canal, to the receptaculum seminis, consisting of the basal and saccular part. Both inseminatory canal and basal part of receptaculum seminis are lined by cuticle, whereas the wall of the sac is formed by cells covered only by long, numerous microvilli. The basal part of the receptaculum seminis joins the ovaries via two lumenless transitory cones. The male reproductive system contains paired testes, in which spermatogonia tightly surround the central cell. The proximal part of the paired vasa deferentia serves as a sperm reservoir, while the distal one has a glandular character. An unpaired, cuticle-lined ejaculatory duct opens into the apex of the aedeagus. The single accessory gland is located asymmetrically at the level of, or slightly posterior to, coxae IV. The structure of the genital papillae, which are topographically related to the genital opening in both sexes, is also briefly described.
利用光学显微镜和电子显微镜对西氏真螨（Acarus siro L.）雌、雄生殖系统的解剖结构和超微结构进行了研究。雌性生殖系统由成对的营养型卵巢组成，其中卵原细胞和卵母细胞通过桥粒与一个大型中央细胞相连。输卵管通向子宫，子宫通向由角质层衬里的产卵前导管，并以纵向裂缝（产卵孔）开口。沿着每条输卵管有一个由一种分泌细胞组成的细长附属腺。交配孔位于身体后缘，通过受精管通向贮精囊，贮精囊由基部和囊状部分组成。受精管和贮精囊基部均由角质层衬里，而囊壁由仅覆盖着长而多的微绒毛的细胞形成。贮精囊基部通过两个无腔过渡锥体与卵巢相连。雄性生殖系统包括成对的睾丸，其中精原细胞紧密围绕中央细胞。成对输精管的近端部分用作精子库，而远端部分具有腺体特征。一条不成对的、有角质层衬里的射精管通向阳茎顶端。单个附属腺不对称地位于第四对基节水平或稍后方。还简要描述了与两性生殖孔在地形上相关的生殖乳头的结构。
