摘　　要：通过田间水稻1代灰飞虱成虫高峰期罩笼接虫传毒试验,结果表明,带毒灰飞虱属持久性传毒型介体昆虫,并随虫量的增加,水稻条纹叶枯病发病呈上升趋势,以400～600头/m2时发病较为明显。浸种试验显示,用25%咪鲜胺EC(使百克)+10%二硫氰甲烷EC(浸种灵)+12.5%吡虫啉SL浸稻种有控虫防病效果。Field and cage experiments were done with adults of grey plant hoppers during its population abundances, results showed that the first generation of Laodelphax striatella was the kind of persistent transmission vector. Rice stripe virus disease became serious along with the increment of the numbers of Laodelphax striatella. The diseases was obvious under the density of grey plant hoppers 400～600/m2. The disease could be under control if rice seeds were soaked in pesticide compound (25%Prochloraz +10%Liuqingjiawan EC +12.5%bichonglin SL) before sowing.
