摘要
经室内毒力测定和田间防治试验结果表明，乙虫脒对麦蚜具有较高的毒力，其ＬＣ５０为５８９６１ｍｇ／ｋｇ。生产应用时，乙虫脒使用量为２５ｇａ．ｉ．／６６７ｍ２左右，对麦蚜控制效果较好，且持效期可达２０天以上。
The results of field traial and toxicity in the laboratory showed that acetamiprid was most toxic to wheat Aphis,It's LC50was 5.8961ppm.At the rate of 25g/667m2(a.i.),acetamiprid was very effective to wheat aphis,and the action persistence to control the pesto for above 20 days.
