摘要： 亚洲小车蝗是我国北方草原和毗邻农田的重要害虫。2002年7月初至中旬先后在赤峰市、多伦县、张家口市、承德市和北京市等北方城市,从北到南突然大量出现亚洲小车蝗的成虫。对不同地区亚洲小车蝗成虫出现时间的分析比较,其雌成虫的卵巢发育状态和迁飞降落的过程以及对此期间在北京采集到的亚洲小车蝗饲养观察等,初步认为亚洲小车蝗具有远距离迁飞的特性。通过观察初步认为,该种蝗虫主要在夜间迁飞,因它具有较强的趋光性,因而在城市中灯光强烈的地方则吸引大量的亚洲小车蝗成虫。

Abstract: Grasshopper(Oedaleus asiaticus)is a vicious pest both to the grass and crops of northern China.During the first half of July 2002,throngs of the insects successively swarmed into Chifeng,Duolun,Zhangjiakou,Chengde,and Beijing.Analysing the exact time grasshoppers appeared at each city or courty,the female insects' reproductive status,the throngs' process of migrating and lighting,and the insects caught and then fed in the laboratory,we realize that the insects often take long-distant migration during the night,and tend to gather around the glowing lamplights of the city due to their characteristics of phototaxis.

Key words: Oedaleus asiaticus, Grasshopper, Nocturnal migration, Reproductive status
