The latter included four periods: pre-landfall, landfall, post-departure with the center located west of 135° E, and post-departure with the center located east of 135° E. Based on adult population monitoring data of S. frugiperda and meteorological data in eastern China before and after the typhoon, Weather Research and Forecasting(WRF) mesoscale numerical simulations, Hybrid Single Particle Lagrangian Integrated Trajectory(HYSPLIT) backward trajectory analysis, and statistical analyses were conducted to elucidate the mechanisms by which the typhoon affected the migratory pathways of S. frugiperda. The results showed that Typhoon Hagupit significantly influenced the hourly migration distance and direction of S. frugiperda. Compared to the pre-typhoon period, the strong southerly winds generated by the typhoon drove the moths to form a south-to-north migratory pathway across eastern China, increased migration speed, and shifted the migration direction from west-northwest to north. When the typhoon center was located over inland East China, the overall migration speed of S. frugiperda reached its maximum, with a peak of 22.93 m/s, and the highest directional concentration of 0.84 was observed. These results indicate that typhoons can promote long-distance migration of S. frugiperda in eastern China. Therefore, population monitoring and early warning during typhoon events should be strengthened, and a regional integrated pest management system should be established. keywords:Spodoptera frugiperda  typhoon  mesoscale numerical simulation  eastern China  migration pattern View Full Text  View/Add Comment  Download reader
