摘　　要：１９９５、１９９６年用１０％溴氟菊酯乳油进行了防治菜青虫的田间药效试验。结果表明：用１０％溴氟菊酯乳油１０００和２０００倍稀释液，药后１天就达到了８０％以上的防效；药后７天，防效仍为９０％以上，各处理的防效均高于２０％甲氰菊酯乳油２０００倍液的防效。The test to control Pieris rapae with 10% brofluthrin EC was conducted in 1995 and 1996.The results showed that the control effect of each test was over 80% after 1 day of using 1000 and 2000 times diluents of 10% brofluthrin EC.The effect of each test was over 90% after 7 days of using 1000 and 2000 times diluents. All the effects were higher than those of 20% fenpropathrin EC 2000 times diluent.So 10% brofluthrin EC is a good pesticide to control Pieris rapae. 〖WT6HZ]
