【摘要】 在实验条件下，观察了发生期及个体大小不一致的3种草原蝗虫对植物高度选择情况．结果表明：蝗虫对植物高度的选择与其本身发生时期及个体大小相关，是物种长期进化的结果，同时，还探讨了蝗虫对植物高度的选择与温度、温度及光照强度之间的关系．更多还原

【Abstract】 Plant height selection in 3 species of grasshoppers were observed under th6 experimental conditions in the Xilin Gol River basin of Inner Mongolia The results showed that Dasyhippus barbipes (F W.) and Pararcyptera microptera meridionalis (Ikonn) prefcr to select the lower sitation on the plant. Oedaleus asiaticus B-Bienko prefer to select the upper situation of plan (Tab.2). The correlation of plant height selction in grasshoppers and climatic factors were analysed in Tab 3更多还原
