西藏油菜田小菜蛾防控策略研究

Research on the Control Strategies for Plutella xylostella in Rapefield of Tibet

小菜蛾Plutella xylostella是西藏主要农耕区油菜田上重要的害虫,严重威胁着西藏油菜产业的安全生产。西藏是我国重要的生态安全屏障,对油菜田小菜蛾的防控要最大限度避免对生态环境的不良影响。为此,提出了相应的防控策略建议:了解掌握油菜主产区小菜蛾的虫源问题,即小菜蛾迁飞与越冬;对油菜主产区小菜蛾进行抗药性监测;推广适合西藏使用的绿色防控技术。通过提出这些针对西藏小菜蛾的防控策略建议,以期为西藏小菜蛾的绿色防控提供理论依据,从而更好地保护西藏的生态环境和油菜产业。

The Plutella xylostella is a significant pest in the rapeseed fields of Tibet's main agricultural areas,posing a serious threat to the safe production of the rapeseed industry in Tibet.Tibet serves as a crucial ecological security barrier of China,and the control of Plutella xylostella in rapeseed fields in Tibet should avoid adverse effects on the ecological environment as much as possible.Corresponding control strategy suggestions are proposed:understanding and mastering the pest source problem of Plutella xylostella in the main rapeseed production areas,namely,the migration and overwintering of Plutella xylostella;monitoring the resistance of Plutella xylostella in these areas;and promoting green control technologies suitable for use in Tibet.These suggestions for the control strategy of Plutella xylostella in Tibet are proposed to provide a theoretical basis for the green control of this pest in the region.
