不同监测工具对水稻二化螟越冬代成虫的监测效果研究

On Monitoring Effects of Different Attracting Insect Devices on Over-Wintered Male Adult of Rice Stem Borer,Chilo suppressalis(Walker)

达县2011年应用水盆型、粘胶型性诱捕器和虫情测报灯3种方法监测水稻越冬代二化螟成虫的效果对比试验表明,粘胶型性诱捕器和虫情测报灯监测越冬代二化螟成虫效果好,优于水盆型性诱捕器,粘胶型性诱捕器诱蛾始见期、终见期、蛾峰期、高峰日等与灯测接近或基本一致,效果稳定,其安装和操作管理简便易行,是适宜基层监测点推广应用的新型监测工具,可对不同地理生态区和区域性的二化螟监测和防控发挥重要的指导作用.

To monitor the emergence period of over-wintered the male adult of rice stem borer,Chilo suppressalis（Walker）,the experiments of three kinds of attracting insect devices,sexual attractant devices with water tray traps and sticky traps respectively,and pest forecast lamp have been conducted in Daxian,Sichuan Province in 2011.The results show that the effects of sexual attractant device with sticky traps is similar to pest forecast lamp in began and end time of moth,moth peak period and peak day,and is better than that with water tray traps.Because the sexual attractant device with sticky traps is simple to install and operate,it is suitable for application in the surveillance units and will play an important role in monitoring and controlling of rice stem borer in various types of ecological areas.
