摘　　要：田间试验表明 :氨基甲酸酯新杀虫剂灭蚜威是一种对麦蚜杀虫活性高的杀虫剂 ,2 5 %灭蚜威EC使用剂量 9 375～ 1 2 5g (a .i.) 667m2 ,药后 3～ 1 0d校正防效山东河南两地分别为 87 64%～ 98 38%和 89 95 %～ 97 66% ,6 2 5g (a .i.) 667m2 药后 7～ 1 0d防效分别为 87 68%～ 92 0 2 %和 88 91 %～94 4 6% ;5 0 %灭蚜威WP使用剂量 1 8 75～ 2 5g (a.i.) 667m2 ,药后 3～ 1 0d防效两地分别为 89 1 7%～99 4 5 %和 93 60 %～ 99 2 3% ,1 2 5g (a.i.) 667m2 药后 7～ 1 0d防效分别为 90 60 %～ 93 5 9%和 92 37%～ 93 5 0 %。A field trial demonstrated that the carbamate insecticide Mieyawei had high insecticidal activity in controlling the wheat aphids. The results of field trials show that the control effects of Mieyawei 25% EC after 3～10 days were 87.64%～98.38% and 89.95%～97.66% at the rate of 9.375～12.5 g (a.i.)/667 m2, and after 7～10 days were 87.68%～92.02% and 88.91%～94.46% at the rate of 6.25 g (a.i.)/667 m2 in Shandong and Henan Provinces respectively. Meanwhile, experiments showed that the effects of Mieyawei 50% WP remained 89.17% ～99.45% and 93.60%～99.23% with applications of 18.75～25 g (a.i.)/667 m2 after 3～10 days and remained 90.60%～93.59% and 92.37%～93.50% with the application of 12.5 g (a.i.)/667 m2 after 7～10 days in both localities respectively.
