摘　　要：为筛选烟粉虱高效防控药剂及其施用技术,采用喷雾和滴灌2种施药方法,测定了70%吡虫啉水分散粒剂、10%溴氰虫酰胺可分散油悬剂、22%氟啶虫胺腈悬浮剂、22.4%螺虫乙酯悬浮剂和20%噻虫胺悬浮剂5种杀虫剂对甘薯烟粉虱的田间防治效果。结果表明:喷雾施用22.4%螺虫乙酯悬浮剂1350和900 g/hm^2以及10%溴氰虫酰胺可分散油悬剂2250和1500 g/hm^2,10 d后对甘薯烟粉虱的防治效果均较好,防效分别为89.25%、90.34%和86.48%、79.22%,且持效期可达21 d;而喷雾施用吡虫啉、噻虫胺、氟啶虫胺腈的各处理防治效果均较差。滴灌施药对甘薯烟粉虱的防治效果均较差。To select the insecticides and application techniques that has high control efficacy on sweetpotato Bemisia tabaci,the control efficacy of five insecticides including 70%imidacloprid WG,10%fenpropafenamide OD,22%fluazifenapyr SC,22.4%spiromethyl SC and 20%thiamethoxam SC were determined,and each insecticide was applied by using spraying and drip irrigation method.The results showed B.tabaci was effectively controlled after spraying 22.4%spirotetramat SC at the dosages of 1350 and 900 g/hm^2,and 10%cyantraniliprole OD at the dosages of 2250 and 1500 g/hm^2 for ten days,and the control efficacies were 89.25%,90.34%,86.48%,and 79.22%,respectively.The persistent effect could last for 21 days.The spraying application of imidacloprid,clothianidin and sulfoxaflor were less effective.Drip irrigation of imidacloprid,clothianidin,spirotetramat,and cyantraniliprole had low control efficacy.The drip irrigation of insecticides for controlling sweetpotato B.tabaci was not recommended.
