摘　　要：[目的]本试验旨在验证氟啶虫酰胺和呋虫胺2者复配使用的合理性及2者复配后对褐飞虱的综合防治效果。[方法]遵循农药杀虫剂室内生物测定试验准则,综合运用室内生物活性测试与田间防治效果试验相结合的方法,全面准确地评价药剂的效果。[结果]试验结果显示,氟啶虫酰胺和呋虫胺2者复配后表现出明显协调增效作用,最优配比确定为1∶3,在此配比下的复配药剂20%氟啶·呋虫胺悬浮剂375 mL/hm2制剂用量下对褐飞虱具有显著的防治效果,施药后7 d防效达到95.65%,明显优于单独使用20%氟啶虫酰胺SC和20%呋虫胺SC。[结论]氟啶虫酰胺与呋虫胺2者复配表现出明显增效作用,适用于水稻田中褐飞虱的有效防控。[Aims]This study aims to verify the rationality of combining flonicamid with dinotefuran and evaluate the integrated control efficacy of them against the brown planthopper(Nilaparvata lugens).[Methods]In adherence to the guidelines for insecticidal bioassay testing,this study employs an integrated approach combining laboratory bioactivity assays with field efficacy trials to comprehensively and accurately evaluate the performance of the pesticides.[Results]The test results revealed that the combination of flonicamid and dinotefuran displayed a pronounced synergistic effect,with the optimal ratio identified as 1∶3.At this ratio,the application of flonicamid·dinotefuran 20%suspension concentrate at a rate of 375 mL/hm2on rice plants showed a significant control effect against the brown planthoppers.On day 7 after treatment,the control efficacy reached 95.65%,which is notably superior compared to flonicamid 20%SC and dinotefuran 20%SC.[Conclusions]The combination of flonicamid and dinotefuran displays a notable synergistic effect,making it suitable for the effective control of N.lugens in paddy fields.
