中文摘要：

选取20种蚱类昆虫作为研究材料,通过标点法选取18个翅脉相关变量对蚱类昆虫后翅翅脉的形态特征进行形态测量学分析。结果表明：得出的3个主成分在前缘脉C起点到臀脉4A点长、前缘脉C顶点到臀脉3A点长、前缘脉C顶点到臀脉11A点长、翅长与翅宽之比上有较高的载荷。

英文摘要：

The morphological characteristics of the hind wing venation of tetrigids were analyzed on the basis of morphometric measurement, with 20 species and 18 different variables selected for this study. Results show that three principal components have a higher load at the length between the starting point of the costal vein and the tip of the fourth anal vein, between the tip of the costal vein and the tip of the third anal vein, and between the tip of the costal vein and the tip of the eleventh anal vein. There exists a contrast between wing length and width.
