摘　　要：为有效控制水稻稻飞虱的为害,选择12种高效低毒杀虫剂,在稻飞虱发生时期于田间进行叶面喷雾,检验各药剂对稻飞虱的防控效果。结果表明,12种杀虫剂在药后3和7 d的防治效果均达90%以上。在单剂中,50%呋虫胺水分散粒剂对稻飞虱的防治效果最高,药后3 d为98.70%,10%三氟苯嘧啶悬浮剂防效次之,为98.10%。复配制剂中,吡蚜酮或烯啶虫胺的复配制剂对稻飞虱的防治效果较好,其中60%吡蚜·噻虫胺水分散粒剂对稻飞虱的防治效果最高,药后3 d防效为99.30%。该试验中12种药剂对稻飞虱均有较好的防控效果,为延缓稻飞虱的抗药性发展,建议防治稻飞虱时注意不同杀虫机制的药剂轮换使用。In order to effectively control the harm of rice planthopper,12 high-efficiency and low-toxicity chemical agents were selected and foliar sprays were carried out during the occurrence of rice planthoppers to test the prevention and control effect of each agent on rice planthoppers in field.The test results showed that the control effects of the 12 kinds of agents have reached more than 90%in 3 days and 7 days after the drug.Among them,the control effect of 50%furofuranamine WG on rice planthoppers was the best at 98.70%in the three days after the drug,followed by 10%trifluoropyrimidine SC,and the control effect reached 98.10%.Compound preparations found in the compound preparations of pyridazone or enidoxazine had achieved good control results.Among them,60%pyrazine and thiamethoxazine WG had the highest control effect on rice planthopper,and 99.30%in the three days after the drug.The experimental results showed that 12 kinds of agents had a good control effect on rice planthoppers,but in order to delay the resistance of rice planthoppers,it was recommended to pay attention to the rotation of agents with different pesticidal mechanisms when controlling rice planthoppers.
