摘　　要：[目的]评价氟吡呋喃酮对柑橘木虱的防治效果,为生产上应用提供科学依据。[方法]依照田间药效试验准则进行田间药效试验。[结果]17%氟吡呋喃酮可溶性液剂50、66.7、100 mg a.i./kg在药后3、7、14 d的田间防效均高于88.5%,甚至高达100%,至药后21 d,防效依旧高达98.4%~100%,表现出良好的速效性和持效性,与对照药剂21%噻虫嗪悬浮剂50.0 mg a.i./kg处理效果相当,对柑橘无药害。[结论]建议在柑橘新梢抽发期,柑橘木虱若虫初发生时,使用17%氟吡呋喃酮可溶性液剂50~100 mg a.i./kg喷雾为宜。[Aims] This study aims to evaluate the field efficacy of flupymdifurone against Asian Citrus Psyllid, Diophorina cirri Kuwayama. [Methods] According to guidelines on efficacy evaluation of pesticides, the field trials were conducted. [Results] The results showed that the control efficacy of flupyradifurone 17% SL against D. cirri at 50-100 mg a.i./kg was over 88.5%, even as high as 100% after 3, 7, 14 d. Furthermore, the control efficacy was still up to 98.4-100% after 21 d. The results showed that the control efficacy, quick availability and long persistence of flupyradifurone against Asian citrus psyllid were equal to those ofthiamethoxam. Moreover, there was no phytotoxicity appeared in the citrus treated with flupyradifurone in our study. [Conclusions] Flupyradifurone was considered as a potential insecticide against citrus psyllid in the field. It is recommended that this novel insecticide will be applied at 50-100 mg a.i./kg by foliar spray, when new flushes of citrus come out and the psyllid nymphsprimary occur.
