本文通过扫描仪对紫胫长夹蝗Choroedocus violaceipes Miller消化道内外壁进行了扫描，观察到消化道各部位的形态特征：食道直管状，由多列纵行脊组成；嗉囊由V形区、V形脊、柳叶脊、扇形脊和不规则脊组成；前胃杯形，由多列纵行脊组成；贲门是由6个凸出于肠壁的Y形结构环围而成；中肠膜质，约占消化道长度的20%；幽门是由12个幽门瓣环围而成；回肠膜质，由6列纵肌环围而成；结肠较回肠细，由6列纵肌组成；直肠是由回肠和结肠延伸下来的6列纵肌组成，其最大的特征是在6列纵肌之间形成6个直肠垫。本文通过观察紫胫长夹蝗消化道的结构特点，对各部位的长度和功能进行了讨论。该研究不仅为蝗虫消化道的形态学研究提供了一个简单的研究方法，也为蝗虫生理和防蝗治蝗提供依据。
 

           The inner and outer walls of the alimentary canal of Choroedocus violaceipes Miller were observed with a scanner. Morphological features of the alimentary canal are as follows; the esophagus is straight and has several rows of longitudinal ridges; the crop is composed of Vshaped bends, Vshaped ridges, lanceolate ridges, fanshaped ridges and irregular ridges; the cupshaped proventriculus has several rows of longitudinal ridges; the cardia are surrounded by 6 Yshaped structures that protrude from the gut wall; the midgut is membranous and comprises 20% of the length of the alimentary canal; the pylorus is surrounded by 12 pyloric valves; the ileum is membranous and surrounded by 6 rows of longitudinal ridges; the colon is thinner than the ileum and also formed of 6 rows of longitudinal ridges; the rectum is formed from 6 rows of longitudinal ridges that extended from the ileum and colon. The main feature of the rectum is that there are 6 rectal pads between the longitudinal ridges. The length and the function of each part of alimentary canal are discussed. This study not only presents a simple method for investigating the insect alimentary canal but also provides a basis for research on grasshopper physiology and locust control.
