摘　　要：田间药效试验结果表明:药后1 d,21%醚菊.吡蚜酮SC 375~600 mL/hm2对稻田白背飞虱的防治效果为72.14%~82.87%,优于吡蚜酮,与醚菊酯相仿;药后7 d,防治效果为95.89%~97.07%,明显优于吡蚜酮、醚菊酯;药后21 d,仍有95.69%~97.52%的防治效果,极显著优于吡蚜酮、醚菊酯。该药剂不同用量对微蛛的影响最大,稍高于对照药剂;对狼蛛的杀伤作用明显低于对照药剂;对球腹蛛基本无杀伤作用。因此21%醚菊.吡蚜酮SC对水稻白背飞虱具有良好的防治效果,速效性好,持效期长,对水稻和田间蜘蛛安全,推荐剂量为375 mL/hm2,防治适期宜掌握在白背飞虱若虫高峰期。The control effects of 21% Etofenprox · Pymetrozine SC to Sogatella furcifera and its safety to major spiders in paddy field were tested.The results showed that the control effect of 21% Etofenprox · Pymetrozine SC at the dosage of 375~600 mL/hm2 against Sogatella furcifera was 72.14%~82.87%,95.89%~97.07%,95.69%~97.52% respectively on the first day,7th day,21st day after spraying,which was better than or similar to that of Permethrin and Pymetrozine.The application of 21% Etofenprox · Pymetrozine SC 375~600...
