摘要
本文报道了作者于１９７６、１９７９年在巴里坤草原自然和罩笼条件下，观察优势种蝗虫取食范围、取食程度等研究结果。根据斑腿蝗亚科蝗虫主要取食双子叶植物，蝗亚科蝗虫取食单子叶植物，而斑翅蝗亚科中一部分种类取食双子叶植物，一部分取食单子叶植物这个事实，提出：斑腿蝗亚科较原始，蝗亚科最进化，斑翅蝗亚科介于两者之间。这种系统是否与蝗虫的头部形态结构有关，值得深入研究。
The feeding habits of six dominant species of Catantopinae,Acridinae and Oedipodinae of Acrididae were studied in 1976 and 1979 in Barkol grassland, Xinjiang Uygur Autonomous Region. Our observations in natural and caged conditions showed that the species of Catantopinae prefer to eat dicotyledon, those of Acridinae prefer to eat monocotyledon, and those of Oedipodinae attack dicotyledon and monocotyledon (Table 1;Figs 2,3,4).These results indicated that the subfamily Catantopinae is a primitive group in the family Acrididae;Acridinae is the most advanced among the three subfamilies;and the Oedipodinae might be the middle envoied group. Further studies on the systematic relationship between the three subfamilies and the morpological types of their head are needed.
