【摘要】 为了明确40%呋虫胺可溶粒剂（SG）对家蝇成蝇的室内防治效果，采用滞留喷洒、空间喷雾、模拟现场试验3种方法对家蝇成蝇进行室内药效测定。滞留喷洒试验结果表明：呋虫胺在不吸收面和半吸收面的持效时间较长，在药效试验国家标准规定的最长时间内，其防治效果仍保持在90%以上，在吸收面的持效时间较短，第45天试虫死亡率低于60%；空间喷施呋虫胺，喷雾3 min后对家蝇出现击倒效果，击倒试虫24 h的死亡率达到100%。模拟现场试验中，施药1 h后试虫击倒率为93%,24 h试虫死亡率为100%。作为防治成蝇的有效杀虫剂，40%呋虫胺可溶粒剂可以采用滞留喷洒方式进行室内施药，也可以采用复配方式增加喷雾药效。更多还原

【Abstract】 In order to determine the control efficacy of dinotefuran 40% SG against domestic fly, laboratory efficacies were evaluated by residual spray, space spray and analogous site test. The results of residual spray test showed that effective periods of dinotefuran 40% SG in the non-absorbing and semi-absorbing surfaces were long, and the control efficacies were more than 90% within the maximum time. The effective period of dinotefuran 40% SG in the absorbing surface was only 30 days and the mortality of the forty-fifth day was less than 60%. When application by space spray, the fly was knocked down at the third minute after the application and the 24-hour mortality rate was 100%. In the analogous site test, the one-hour knockdown rate was 93% and 24-hour mortality rate was 100%. As an effective insecticide against adult fly, dinotefuran 40% SG could be applied by residual spray or synergistic insecticide mixtures.更多还原
