摘要
解剖观察表明,泽陆蛙消化道分段明显,起自口,经过口咽腔、食道、胃、小肠(十二指肠、空肠、回肠)、大肠(直肠),末端开口于泄殖腔。泽陆蛙消化系统的结构与食肉习性相适应,雌体和雄体消化系统各个组成部分的测量绝对值有较大差异。泽陆蛙的主要食物为农林害虫和卫生害虫,对于维持生态平衡和环境卫生起着积极的作用。
Digestive system of Fejervarya Multistriata was observed by using anatomy method. Its digestive system consists of digestive tracts and glands. The digestive tracts begin with mouth, then oropharyngeal cavity, esophagus, stomach, small intestine （duodenum, jejunum and ileum） and large intestinum （rectum）. The digestive glands are mainly composed of the liver and the pancreas. The structures of digestive system of Fejervarya Multistr/ata are suitable to their functions. Though the measured absolute sizes of every part of the digestive system are quite different between the female and the male, the relative sizes are approximate. Fejervarya Multistfiata＇ s main foods are agricultural, forestry and hygiene pests, so it plays a positive role in promoting agricultural and forestry development and keeping ecological equiUibrium and conditional hygiene.
