| 摘 要： | 疥螨消化系统由咽、食道、中肠、１对侧囊、结肠、直肠、肛门以及唾腺组成。应用透射电镜，可将中肠和侧囊壁上皮细胞分为鳞状细胞期、柱状细胞期、核变性圆细胞期和全变性细胞期等４种不同生理功能状态。可将唾腺细胞分为Ｉ期、Ⅱ期和Ⅲ期等３种不同生理功能时期。食道和中肠及侧囊内含物为絮状物。直肠前段肠壁具有较多微管。

| Abstract: | The digestive system of Sarcoptes scabiei is described by means of light and electron microscopy. It may be divided into pharynx, esophagus, midgut, paired lateral caecae, colon, rectum, anus and salivary glands. The epithelial cells of midgut and lateral caecae are divided into aqamous cells, columnar cells, round cells undergoing nuclear degeneration and completly degenerated cells, which show different functions. The large paired salivary glands lie anterior and lateral to the anterior midgut. They consist of about 4-6 large cells which may be divided into three stages. |
