摘　　要：解剖了日本蚱（Tetrix japonica）的消化系统,并对其取食习性进行了分析。结果表明,日本蚱消化道分为前肠、中肠、后肠,前肠最短,由食道、明显膨大的嗉囊和前胃构成;中肠长度居中,前端有6条较粗短的胃盲囊围绕在嗉囊周围;后肠最长,分回肠、结肠、直肠三部分。马氏管发达,约为70-100根。食物残渣多分布在中肠、后肠,多为绿色或黄绿色绒状植物纤维,伴有少量沙土粒。日本蚱为植食性,主食幼嫩草本植物、苔藓等,有时会进食沙土粒。Digestive system of Tetrix japonica was anatomied and its feeding features was analysed. The results showed that digestive tract of T. japonica was divided into three parts： foregut, midgut and hindgut. Foregut, consisting of esophagus ,ob- viously intumescent jabatby and cardia, was the shortest. Midgut was in the middle in length and six thick and short Gastric caecas around the jabatby were in the midgut＇s front. Hindgut was the longest and consisted of three parts： ileum, colon and rectum. Malpighian tubes developed which were about 70-100 in number. Most of food particles, green or yellow-green fili- form plant fiber with some small grains of sand and soil, were in the midgut and hindgut. T. japonica was a kind of plant- feeding insect feeding young herbage, moss and sometimes some small grains of sand and soil.
