摘　　要：田间试验表明 ,1 9%甲氰·阿维EC 9 5g (a .i.) 667m2 对美洲斑潜蝇LiriomyzasativaeBlanchard的校正防效药后 3～ 1 1d为 87 2 2 %～ 91 3 2 % ;7 1 2 5g (a.i.) 667m2 药后 3～ 1 1d为 81 2 9%～ 85 1 0 % ;9 5g (a .i.) 667m2 药后 3～ 1 1d防效显著优于单剂甲氰菊酯 ,药后 3～ 7d显著优于单剂阿维菌素 ,药后11d防效与阿维菌素无显著区别。 1 5 %甲氰·阿维EC 7 5g (a .i.) 667m2 对美洲斑潜蝇的校正防效药后3～ 1 1d为 85 5 9%～ 89 0 9% ;5 62 5g (a .i.) 667m2 药后 3～ 1 1d为 77 1 5 %～ 85 95 %。 1 0 %甲氰·阿维EC 7 5g (a .i.) 667m2 对美洲斑潜蝇的校正防效药后 3～ 1 1d为 85 5 9%～ 89 0 9% ;5 62 5g (a .i.) 667m2 药后 3～ 1 1d为 77 1 5 %～ 85 95 %。混剂的药效基本随有效成分含量的提高而提高。The field tests demonstrated that control effects of the mixture fenpropathrin+abamectin 19% EC at the rate of 9.5 g (a. i.)/667m2 to Liriomyza sativae Blanchard in 3～11days after application was 87.22%～91.32%, which was significantly better than that of fenpropathrin, and its effect in 3～7 days after application was significantly better than that of abamectin, but after 11 days there was no difference among them. The control effects at the rate of 7.5 g(a.i)/667m2, 5.625 g(a. i.)667m2 and 3.75 g(a. i.)/667m2 to L. sativae in 3～11 days after application was 85.59%～89.09%, 77.15%～85.95% and 78.52%～79.96%, respectively. The efficacy of the mixture increased with the increase of the content of active ingredients.
