摘　　要：在2007和2008每年7—8月对天津草坪蝗虫种类进行调查,并经若虫饲养与种类鉴定、特征比较得知:花胫绿纹蝗若虫头顶前端锐角形,有梯形的头侧窝、无前胸腹板突等构造可以区别于头顶前端平截,无头侧窝、有前胸腹板突的长翅素木蝗及头顶前端园钝,无头侧窝、有前胸腹板突、后足腿节内、外下膝侧片有锐刺状突起的中华稻蝗若虫。东亚飞蝗若虫无前胸腹板突、头顶前端园钝,复眼下方有一深色斑可区别其它几种若虫。Investigation on grasshopper nymphae of Ailopus tamulus （Fabricius） 1798, Shirakiacris shirakii （I. Bolivar, 1914）, Oxya chienesis Thunberg 1831 on turf grass were done at Tianjin during July and August of 2007, 2008. The results obtained after nymphae rearing and adult recognizing and comparison of characteristics of this experiment showed that： A. tamulus distinguished from S. shirakii mainly by its apex of vertex which was an acute angle in shape, ladder-shaped lateral fovea, and no process on ventral side of prothorax. S. shirakii （I. Bolivar, 1914） had a truncate - shaped apex of vertex, no any lateral fovea existing, a process was on ventral side of prothorax. Oxya chienesis Thunberg, 1831 had a curve - shaped apex of vertex, no lateral fovea existing and had a process on ventral side of prothorax and differed from A. tamulus.
