摘要: 本研究主要采用透射电镜观察粉尘螨Dermatophagoides farinae (Hughes)生殖系统超微结构。粉尘螨雄性生殖系统是由精巢、 输 精管、 附腺、 射精管、 交配器官及附属交配器官组成。精巢内可同时有精子发育各阶段的细胞。精子无核膜、 核染色质聚集成束、 线 粒体缺乏典型的嵴、 胞质内有平行排列的电子致密薄片等为其特征性结构。雌性生殖系统由交合囊、 交合囊管、 储精囊、 囊导管、 卵 巢、 输卵管、 子宫及产卵管构成。卵巢内可见含多个细胞核的中央细胞, 其周为卵母细胞等生殖细胞。该研究丰富了对粉尘螨生殖系统 结构的认识。

Abstract: The ultrastructure of the reproductive system for male and female Dermatophagoides farinae (Hughes) was observed with transmission electron microscopy (TEM). The male reproductive system of D. farinae consists of testis, vasa deferentia, accessory gland, ejaculatory duct, copulatory organ and accessory copulatory organs. All stages of spermatogenesis exist simultaneously in the testis. A typical sperm is characterized by short of nucleus, chromosomal material in threads, mitochondria without typical cristae, and cytoplasm with conspicuous parallel electron-dense lamellae. The female reproductive system consists of copulatory bursa, ductus bursae, receptaculum seminis, ducti receptaculi, ovaries, oviducts, chorion glands, and the ovipositor. The ovary contains a large multinucleated central cell surrounded by oocytes and other germ cells. The results broaden our understanding of the reproductive system of D. farinae.
