摘　　要：为了筛选拌种防治二点委夜蛾的有效药剂,并明确其对玉米种子萌发的安全性。本文通过培养皿法和室内盆栽试验比较了9种不同类型杀虫剂拌种对玉米种子萌发的影响以及保苗效果。结果表明,60%溴氰虫酰胺SC和20%氯虫苯甲酰胺SC拌种处理效果较好,保苗效果分别达到90.02%和70.07%,可将死苗率控制在10%以内,被害指数控制在20%以内,且对玉米出苗安全。因此,60%溴氰虫酰胺SC和20%氯虫苯甲酰胺SC可作为拌种防止玉米二点委夜蛾为害的有效药剂。The aim of this study is to screen effective seed dressing pesticides for Athetis lepigone,and clarify its safety for maize seed germination.Effects of nine different types of pesticides by seed dressing on seed germination and seedling protection were investigated by petri dish method and indoor potted trial.The results showed that the seedling protecting effect of 60% cyantraniliprole SC and 20% chlorantraniliprole SC by seed dressing were 90.02% and 70.07%,respectively.The dead seedling rate was lower than 10%,and the damage index was lower than 20% after treament with these two pesticides.Moreover,they are safe on the seed germination of maize.Therefore,60% cyantraniliprole SC and 20%chlorantraniliprole SC can be used as effective agents against A.lepigone by seed dressing.
