Abstract:

[Objectives]  To develop an effective tool to monitor the population dynamics of Mythimna separate. [Methods]  19 verticalpointing searchlighttraps 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.
