柏氏禽剌螨的内部构造

Studies on the internal structure of gamasid mite (Ornithonyssus bacoti)

本文报告用石蜡切片和我室建立的冰冻厚片透明法研究柏氏禽刺螨的内部构造。其呼吸系统的气管分为5级,即主气管、副主气管、细气管、微细气管和微气管,后者达细胞;其消化系统相对简单,由咽、薄壁的食道、1个相对小的中肠及连接中肠的3对盲囊,1个小的后肠、直肠囊和肛门组成。生殖系统包括单个卵巢、输卵管、子宫受精囊、生殖孔及1对附腺。冰冻厚片透明法已成功地用来观察柏氏禽刺螨的生殖营养周期。

The present study is reported to describe the internal anatomical structures of gamasid mite, Ornithonyssus bacoti by the paraffin section, and shick freezing transparent section which was setup in our Iaboratory. The trachea of the O. bacoti is divided into five parts: the main tracheal trunk, accessory main tracheal trunk, fine trachea, tiny trachea and capillary trachea supplying on the cells. The digestive tract of O. bacoti is a relatively simple thing. It is comprised of a pharynx, a thin walled esophagus, a rather small midgut, three pairs of cecum attaching to the midgut, a small hindgut, the rectal sac and anus. The female system consists of one ovary, a short oviduct, an uterus, and genital pore, two accesorysglands and a spermatheca. The gonotrophic cycle of the mite has been demonstrated by thick freezing transparent sections prepared from femal gamasid mite (O. bacoti.)
