摘　　要：通过对棉蝗Chondracris rosea rosea(De Geer)的腹部解剖观察,并与非洲飞蝗Locusta migratoria migratorioides(Reiche et Fairm.)以及美国蝗Dissosteira carolina Linnaeus进行了比较,棉蝗腹部具有许多不同于它种的特异结构,主要是:(1)雌蝗的第一、第二腹节的背板两侧各有1个半膜质区。(2)雌蝗的侧生表皮内突长约0.90—1.5cm,比飞蝗长。(3)雄蝗的阳茎表皮内突呈“U”字形,两端尖细,并向外倾斜。(4)阳具基背片构造比飞蝗简单。(5)阳具背叶的远侧部有4个小突起,与美国蝗有些相似。(6)雌雄两性棉蝗每节腹板的前角处有一对较飞蝗为尖的表皮内突。By dissecting and observing the abdomen of Chondracris rosea rosea and comparing it with Locusta migratoria (Reiche et Fairm) and Dissosteira carolina it has been found that apart from the general morphological features these species of locusts have in common, the abdomon of Chondracris rosea rosea posseses many specific structures which differ from those of the other species. They are as follows: 1. There is a semimembrane area on each side of the terga of the first and second urites of the female Chondracris rosea rosea 2. The lateral apodeme of the female Chondracris rosea rosea, is about 0.90--1.5cm, which is longer than that of Locusta migratorioides. 3. The aedeagal apodeme of the male Chondracris rosea rosea has a 'U' form, thin and pointed at the two ends, and inclines outwvards. 4. The stucture of the epiphallus is simpler than that of Locusta migratoria migratorioides. 5, On the farther lateral sides of the back phallomeres there are 4 small protuberances, Which is similar to that of Dissosteira carolina. 6. In the front corner of the sterna of both the male and the female Chondracris rosea rosea, there is a pair of apodemas which are longer than those of Locusta migratoia migratorioides.
