摘　　要：对分布在我国西北及西南三科五属八种蝗虫前肠形态的分类学价值进行了研究．蝗虫前肠依表皮脊及刺的特征可区分为四区，这四区形态及贲门瓣结构与其它分类性状呈正相关，可作为分类性状运用．以亮绿染色后封片，体视摄影的应用。The taxonomical significance of the foregut armatures of 8 species belonging to 3 families (Pamphagidae, Chrotogonidae, Pygmorphidae) has been discussed with 8 illustrations. Based on the type of arrangement of the ridges and cuticular armatures of the foregut, four zones ZⅠ-ZⅣ can be easily distinguished. The morphology and the structure of proventricular valves of the four zones exhibit extensively direct proportion with variation of morphology, which can be used as a taxonomic character. The study of foregut armature was facilitated by using micro photography.
