滇西北地区草地贪夜蛾区域生态防控构想

Regional ecological control of Spodoptera frugiperda in Northwest Yunnan

  • 摘要: 云南是中国草地贪夜蛾危害最重的省份,也是境外草地贪夜蛾向中国内地迁移的首站. 在云南开展草地贪夜蛾区域防控,对于破解云南省草地贪夜蛾大范围危害难题,具有现实性全局性指导意义. 作者开创性提出区域生态防控思想,即从景观生态学的原理和方法出发,根据当地生态环境条件和草地贪夜蛾的发生发展规律,对防控区域加以片区划分,综合多种防控手段,对草地贪夜蛾开展区域层面可持续绿色防控. 研究以滇西北地区草地贪夜蛾区域防控为样本,结合当地生态环境条件、寄主种植制度及草地贪夜蛾发生特征,将滇西北地区分为5个生态防控区,探讨了在滇西北地区开展区域生态防控的思想、原则和方法,为在云南开展草地贪夜蛾防控提供了新思路.

     

    Abstract: Regional prevention and control refers to the deployment of prevention and control of Spodoptera frugiperda at regional level. Yunnan Province is a serious disaster area of S. frugiperda and also the bridgehead for the migration and expansion of the alien pest to the inland areas of China. The regional prevention and control of S. frugiperda has realistic and overall guiding significance for solving the problem of large-scale damage caused by S. frugiperda in Yunnan Province. The concept of regional ecological prevention and control was put forward. Northwestern Yunnan, as a regional control sample of S. frugiperda, was divided into five ecological prevention and control areas based on the principles and methods of landscape ecology. By combining the ecological environment conditions of Northwestern Yunnan with the occurrence regularity of the S. frugiperda, the ideas and principles of regional ecological prevention and control were discussed to provide a new idea for S. frugiperda control.
