摘　　要：应用二化螟性诱剂对 2代雄蛾进行大面积诱捕试验 ,结果表明 :诱捕 7、15天后 ,诱捕中心区、边缘区比CK区单盆诱蛾量分别降低 88.67%、71.0 9%和 84.72 %、69.72 % ;2 5天后中心区无雄蛾存在 ,边缘区几乎无雄蛾存在。诱捕 15天后 ,中心区、边缘区与CK1 及诱测灯CK2 之间单盆日诱蛾量均呈极显著差异。二化螟性诱剂诱蛾效果 7天后明显高于诱测灯 ,而在连续诱杀 15天后 ,日均诱蛾量完全与诱测灯相同。诱捕中心区、边缘区、CK1 区的水稻丛害率分别为 0 .16%、0 .3 9%和 0 .71% ,前两者明显低于 1%的危害指标。研究表明 ,二化螟性诱剂可作为该虫的测报和发生期等的预测手段 ;同时建议在白湖圩区推广应用二化螟性诱剂来防治二化螟 ,可真正起到节本、简便、增产、增效 。The experiment in killing male month of second general of rice stem borer with the sex attractant indicated that the number of month per basin reduced to 88.67% and 71.09%, and 84.72% and 69.72% in the center place and edge area of attractant after seventh and fifteen day of treatment, compared with CK respectively, and there were no and almost no male month in the center place and edge area after twenty-fifth day. There were significant differences in the number of month per basin among center, edge place and CK after 15th day of treatment. The effect of sex attractant on killing the male month was obviously higher than that of light trap after 7th dayof treatment, but no any difference after 15 th. The rate of rice damaged was 0.16%, 0.39% and 0.71% in the center, edge place and CK respectively. So the sex attractant could be used as the forecast of rice stem borer occurrence.
