摘要
[目的]推广应用性信息素诱杀技术控制烟草斜纹夜蛾(Spodoptera litura Fabricius)。[方法]按26m×26m(1个/676 m2)的密度在田间设置3层斜纹夜蛾性诱剂(诱捕器),进行田间防治试验。[结果]在该密度下,通过性诱剂对雄蛾的诱杀,田间卵量减少了62.16%,虫量与常规防治的对照区相当,控制作用持续、稳定,效果显著。使用面积越大,效果越好。[结论]利用该技术可有效控制烟草斜纹夜蛾,减少农药使用量80%以上,具经济、安全、高效的特点,可将其纳入烟草斜纹夜蛾的防治技术体系之中。
[Objective]The paper was to promote using synthetic sex pheromone lures to control tobacco cutworm moth（Spodoptera litura）.[Method]Three layers of pheromone traps for tobacco cutworm moth were set in the field at the density of 26 m×26 m（one suit/676 m2）to carry out field control test.[Result]The amount of eggs was reduced by 62.16%after trapping by sex pheromone under the density,and the larvae population was equivalent to those in the conventional control field with pesticides,the control effect was continuous,stable,and significant.The larger the control area was,the better the effect was.[Conclusion]Using sex pheromone could effectively control tobacco cutworm moth and reduce pesticide usage for over 80%with economic,safe,efficient features,which should be incorporated into the technical prevention and control system of tobacco cutworm moth.
