Abstract

Abstract:

【Objective】The fall armyworm, [Spodoptera frugiperda (J. E. Smith), FAW] is a significant migratory pest newly invaded China. It was discovered in Jiande City of Zhejiang Province on 8 May 2019, and thereafter spreaded rapidly throughout Zhejiang Province. A better understanding of the distribution of the source areas and the migration path of FAW populations will be beneficial for the monitoring, early warning and the source control of this pest in Zhejiang Province. 【Methods】The migratory routes and weather fields for the newly invasive population in Zhejiang Province were analyzed by using a trajectory simulation approach, combined with flight behaviour and meteorological data.【Result】According to the larval developmental period, the first batch of FAW adults may immigrate into Zhejiang Province from 26 to 30 April. In late April, the southwesterly airflow passed through most part of southern and eastern China, providing a carrier airflow for the FAW migrants, while low temperature barriers, rainfall and sinking airflow can cause a forced landing of the FAW. The effective source of the FAW invasive population in Jiande City, Zhejiang Province is mainly distributed in eastern Guangxi.【Conclusion】This research results lay a basis for the monitoring, early warning, scientific prevention and control of the spring immigrants of FAW in Zhejiang Province.

Key words: Spodoptera frugiperda (J. E. Smith), weather condition, migratory route, trajectory analysis, insect source area

摘要：

【目的】草地贪夜蛾是新入侵我国的重要迁飞性害虫,2019年5月8日浙江省建德市发现草地贪夜蛾入侵为害,已在全省迅速扩散蔓延。明确浙江省发现的草地贪夜蛾种群的虫源地分布及迁飞路径,对浙江省草地贪夜蛾的监测预警及源头治理有重大意义。【方法】利用基于WRF模式的昆虫三维轨迹分析程序,结合草地贪夜蛾的飞行行为参数和气象资料,对入侵浙江的草地贪夜蛾的迁飞路径及天气背景场进行了模拟分析。【结果】根据幼虫发育历期推算,4月26日–30日可能有首批草地贪夜蛾成虫迁入浙江省。4月下旬,西南低空急流贯穿华南及华东大部,可为草地贪夜蛾迁飞提供运载气流,而低温屏障、降雨和下沉气流可导致草地贪夜蛾的迫降。入侵浙江省建德市草地贪夜蛾种群的有效虫源地主要分布在广西东部。【结论】本研究结果为浙江省草地贪夜蛾春季迁入种群的监测预警和科学防控提供了依据。
