摘　　要：进行2%阿维菌素乳油防治水稻稻瘿蚊田间药效试验,试验用量分别为75、150、225gai/hm2,药后20d防治效果分别达93.69%、96.59%、98.59%,与对照药剂10%益舒宝颗粒剂1650 gai/hm2处理的防效相当。建议生产上以150-200gai/hm22%阿维菌素乳油作为防治水稻稻瘿蚊的有效药剂轮换使用。In the field experiment, the effects of 2% avermectin EC on controlling rice gall midge were studied. Different dosages of 2% avermectin EC including 75 g ai/hm^2, 150 g ai/hm^2 and 225 g ai/hmz were applied on rice, and the control effect was 93.69%, 96.59% and 98. 59%, respectively, in 20 days after application, which was the same as that of the CK, 1650g ai/hm^2 10% ethoprobos FG. So, 2% avermectin EC with 150-200 g ai/hm^2 could be used for rotating 10% ethoprohos FG to control rice gall midge in production.
