摘　　要：2004年对江苏扬州郊区露地蔬菜豌豆彩潜蝇种群动态进行了调查,并就氯氰菊酯乳油、5%抑太保乳油、10%吡虫啉粉剂等3种常用农药对豌豆彩潜蝇的防虫效果进行了比较。结果表明:豌豆彩潜蝇主要分布在菊科、十字花科、豆科和葫芦科等蔬菜上,以莴苣、生菜、萝卜、花椰菜、豌豆、蚕豆发生较严重。10%氯氰菊酯乳油2 000、3 000倍液于用药后7、11 d的防效分别在85%和80%以上,10%吡虫啉粉剂1 000倍液于用药后11 d的防效也在80%以上。The population dynamics of Chromatomyia horticola in outdoor vegetables were preliminarily investigated in Yangzhou area, Jiangsu in 2004. It occured seriously in Compositae, Cruciferae, Leguminosae and Cucurbitaceae, especially in lettuce, radish, cauliflower, pea and horsebean. The field evaluation of the three main inseetieides, 10% cypermethrin, 5 % chlorfluazuron, 10% imidacloprid for C. horticola was made. The results suggest that the control efficacy of 10% cypermethrin 2 000× and 10% cypermethrin 3 000× was higher than that of 85% and 80%, respectively, both at 7 and 11 days after application of the insecticide. The efficacy of 10% imidacloprid 1000× was higher than 80% at 11 days after the application.
