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 ,与环境友好的目的 Large-area trapping experiments were carried out on the second-generation male moths by means of sex-attractant. The results showed that after trapping for 7 days and 15 days, the single-trap moths in the central and marginal areas decreased 88.67% and 71.0 9%, respectively 84.72% and 69.72% respectively. After 20 days, no male moths were found in the central area and almost no male moths existed in the marginal area. After 15 days of trapping, the amount of single-trap moths in the center, marginal zone and CK1 and CK2 were all significantly different. The results showed that the induced moths were significantly higher than the induced light after 7 days and the average daily induced moths were the same as the induced light after 15 days of continuous trapping. Trapping the central area, the marginal zone, CK1 area of ​​rice damage rates were 0.16%, 0.39% and 0.71%, the first two significantly lower than 1% of the hazard indicators. Studies have shown that the sexually attractant of the rice stem borer can be used as a means of forecasting and the occurrence of the worm and other means of prediction; also recommended in the Baihu polder area to promote the use of sex-induced resistance to rice stem borer Chilo suppressalis, can really play a section , Simple, increase production, increase efficiency, and environment-friendly purposes
