诱捕器对烤烟斜纹夜蛾的防治效果研究

Control Effect of Tobacco Spodoptera litura by Sex Pheromone Trap

[目的]探讨诱捕器对烤烟斜纹夜蛾的防治效果。[方法]调查并分析了斜纹夜蛾性诱剂、化学药剂和空白对照处理对烤烟斜纹夜蛾的防控效果。[结果]斜纹夜蛾性诱剂诱捕蛾量呈明显的高峰期和峰次。性诱剂防控区比空白对照区的虫口密度平均减退70.5%;比常规药剂控制区的虫口密度平均减退7.1%,降低成本35.6%。[结论]斜纹夜蛾性诱剂对烤烟斜纹夜蛾有较强的诱测和防控作用,可作为监测和防控斜纹夜蛾的有效措施推广应用。

[Objective] The aim was to study the control effect of tobacco Spodoptera litura by sex pheromone trap.[Method] Preventing and controlling effects of tobacco Spodoptera litura by sex pheromone trap,chemical spraying and blank group were investigated and analyzed.[Result] Sex pheromone trap showed an obvious peak period and peak time to induce Spodoptera litura.The population density of Spodoptera litura treated by sex pheromone trap was averagely 70.5% less than blank group area,while it was averagely 7.1% less than chemical spraying area.Compared with chemical spraying,the production cost of sex pheromone trap was decreased by 35.6%.[Conclusion] Sex pheromone trap has strong preventing and controlling effects on tobacco Spodoptera litura,so it could be taken as an effective measure to monitor and control Spodoptera litura.
