摘要
斜纹夜蛾是烟草生长中后期的一种重要暴食性害虫。采用常规喷雾法研究了5种化学杀虫剂对烟田斜纹夜蛾幼虫的防治效果,结果表明:5种杀虫剂以10%溴氰虫酰胺可分散油悬剂1 500倍液的效果最好,施药后5、7、14 d对斜纹夜蛾幼虫的防治效果分别为86.0%、91.4%、100.0%。150 g/L茚虫威悬浮剂4 000倍液对斜纹夜蛾幼虫也具有较好的防治效果,施药后7、14 d的防治效果分别为90.1%、91.1%。烟田防治斜纹夜蛾以10%溴氰虫酰胺可分散油悬剂2 000~3 000倍液为宜。
Prodoptera litura(Fabricius)is a gluttony pest in middle and late gro^h stage of tobacco. The control effects of five chemical insecticides on P. litura (Fabricius)were researched using method of convention spray. The results indicated that among tested five insecticides, 10% cyantraniliprole dispersible oil suspension diluted 1 500 times the showed the best control effect ,and the mortality rate of P. litura(Fabricius)larva were up to 86.0% ,91.4% and 100.0% after 5 days ,7 days, 14 days correspondingly.150 g/L indoxacarb suspending agent diluted 4 000 times showed good control effect,and the mortality rate of P. litura(Fabricius)larva were up to 90.1% and 91.1% after 7 days and 14 days correspondingly. 10% cyantraniliprole dispersible oil suspension should be diluted 2 000 to 3 000 times to control the P. litura(Fabricius) larva in tobacco field.
