摘要
【目的】为探索粘虫Mythimna separata Walker成虫种群监测的有效工具。【方法】2014年在全国17个省(市、区)设立了19个高空测报灯观测点,通过各地全年系统监测逐日蛾量。【结果】掌握了粘虫全年南北往返迁飞的种群发生动态,总结出了粘虫全年发生代次(时间)、发生区域和发生数量。【结论】高空测报灯诱测数据反映了粘虫各代次发生时间规律,反映了粘虫种群数量变动规律,体现出区域间种群数量相关性,种群数量变动关系密切的因子有待探讨。此方法为做好其他迁飞性害虫的监测提供了可借鉴的手段和方法。
[Objectives] To develop an effective tool to monitor the population dynamics of Mythimna separate. [Methods] 19 vertical-pointing searchlight-traps were built and installed in 17 provinces in 2014. [Results] Moth abundance, number of generations, distribution and population size were monitored daily at all monitoring stations. [Conclusion] The correlation between population size and occurrence in different regions may be important for monitoring regional population dynamics and improving the accuracy of temporal and spatial forecasting of M. separate outbreaks. Our research may also provide a reference for monitoring other migratory pests.
