摘　　要：菜蚜是蔬菜栽培中发生量最大、危害期最长的重要害虫。对不同配比的尿洗合剂对菜蚜的拒食活性、触杀毒力和控制效果进行了研究。结果表明:尿素:洗衣粉:水按4:1:100配比的尿洗合剂效果最好,对菜蚜24h拒食率为75.08%,96h校正死亡率为86.7%,7天的虫口减退率为55%。Mustard aphid is the most frequently seen pest that can yield the longest-lasting damage in vegetable planting. The antifeed activity, toxicity and control effects of urinary wash mixture with different proportion of urea and washing powder on mustard aphid were studied in this paper. The results showed that the urinary wash mixture with the proportion of urea （4）：washing powder （1）：water （100） had the best effects on mustard aphid. The antifeed rate in 24 h, rectified mortality in 96 h and population dropping rate in 7 d of mustard aphid were 75.08%, 86.7% and 55% respectively.
