| 摘 要： | 为筛选出高效、低毒的杀虫剂防治甜菜夜蛾和小菜蛾，对15种药剂进行了田间药效评价试验。甜菜夜蛾试验结果表明，10%溴氰虫酰胺、30%茚虫威和50%丁醚脲防治效果较好且药效持久，药后7 d 防效均在91%以上。小菜蛾防治试验结果表明，30%茚虫威的防治效果最好，药后3 d、7 d 的防效分别为87.58%、90.14%。

| Abstract: | In order to select high effects and low toxicity pesticides against Spodoptera exigua and Plutella xylostella, effi-cacy of 15 pesticides was evaluated via field experiments. The results of control effects on Spodoptera exigua indicated that 10% Cyantraniliprole, 30% Indoxacarb and 50% Diafenthiuron had good and lasting potency, the control efficacy over 91% during 7 days. The results of control effects on Plutella xylostella indicated that the best control efficacy was 30%Indoxacarb, which efficacy was 87.58%, 90.14% after 3 days and 7 days. |
