摘　　要：为探明危害贵州黑麦草人工草地和混播草地的叶蝉种类及发生动态,为该类害虫的防治提供参考,采用网捕法调查2种草地的叶蝉种类和发生动态。结果表明:危害黑麦草人工草地和豆禾混播草地的叶蝉种类主要有7种,分别是黑尾叶蝉[Nephotettix cincticeps(Uhler,1896)]、棉奥小叶蝉[Austroasca vittata(Lethierry,1884)]、烟草嘎叶蝉[Alobaldia tobae(Matsumura,1902)]、印度顶带叶蝉[Exitianus indicus(Distant,1908)]、二点叶蝉[Macrosteles fascifrons(Stl,1858)]、橙带铲头叶蝉[Hecalus porrectus(Walker,1858)]和异长柄叶蝉[Alebroides discretus Chou&Zhang,1987];危害豆禾混播草地的叶蝉主要是除印度顶带叶蝉外的其他6种。其中,棉奥小叶蝉和烟草嘎叶蝉为优势种群;棉奥小叶蝉种群数量在黑麦草草地呈双高峰型(分别在7月2日和8月15日),在混播草地上发生较轻;烟草嘎叶蝉在黑麦草草地上发生较轻,在7月中旬有1个发生高峰,在混播草地上则呈多峰型(集中于7月中旬至8月底)。The species and occurrence dynamic of leaf hoppers to damage ryegrass and grass-legume mixed artificial grassland were investigated by the netting method to provide a reference for control of leaf hoppers in ryegrass and grass-legume mixed artificial grassland in Guizhou. Results： There are seven species of Nephotettix cincticeps , Austroasca vittata , Alobaldia tobae , Eacitianus indicus , Macrosteles fascifrons, Hecalus porrectus and Alebroides discretus to damage ryegrass and grass-legume mixed artificial grassland. There are six species of Nephotetti：c cincticeps, ustroasca vittata, Alobaldia tobae, Macrosteles fasci frons, Hecalus porrectus and Alebroides discretus to damage grass-legume mixed artificial grassland. Austroasca vittata and Alobaldia tobae are dominant populations. The population quantity of Austroasca vittata shows a double peak type （in 2,July and 15, August） in ryegrass artificial grassland but is less in grass-legume mixed artificial grassland. Alobaldia tobae has a occurrence peak in the middle ten days of July in ryegrass artificial grassland but shows a multi-peak type from the middle ten days of July to the end of August.
