摘　　要：为明确静电喷雾器在烟草害虫防治中的应用潜力,对比测定了2种杀虫剂经静电喷雾器和电动喷雾器喷施后对斜纹夜蛾和烟青虫的田间防效及杀虫剂残留量的动态变化。结果表明:①静电喷雾器喷施5%甲维盐水分散粒剂(Water dispersible granule,WG)和5%高氯甲维盐微乳剂(Microemulsion,ME)对斜纹夜蛾和烟青虫的田间防效显著高于电动喷雾器。②经静电喷雾器和电动喷雾器喷施后,2种杀虫剂在烟叶和土壤中的杀虫剂残留量均随着时间的推移而降低,且在喷施处理后相同时间时,静电喷雾器喷施处理烟叶中的杀虫剂残留量显著高于电动喷雾器喷施处理,静电喷雾器喷施处理烟垄土壤和烟沟土壤中的杀虫剂残留量显著低于电动喷雾器喷施处理。③2种杀虫剂经静电喷雾器喷施处理的烤烟产量和产值均显著高于电动喷雾器喷施处理。In order to compare the application potential of electrostatic insecticide sprayers for pest control in tobacco fields,the control efficacies and the dynamic changes of residue levels of two insecticides against Spodoptera litura and Helicoverpa assulta sprayed by electrostatic and electric sprayers were tested.The results showed that:1)The control efficacies against S.litura and H.assulta of 5%emamectin benzoate WG and 5%emamectin perchloric ME sprayed with the electrostatic sprayers were significantly higher than those achieved with the electric sprayers.2)After electrostatic or electric spraying,the residue levels of the two insecticides in tobacco leaves and soil of tobacco fields decreased with time.In addition,the residue levels of insecticides sprayed by the electrostatic sprayers in tobacco leaves were significantly higher and the residue levels in ridge soil and furrow soil of tobacco fields significantly lower than those sprayed by the electric sprayers.3)The yield and output value of flue-cured tobacco treated with the two insecticides sprayed by the electrostatic sprayers were significantly higher than those by the electric sprayers.
