摘要： 稻纵卷叶螟是滇东南稻区常年为害较重的水稻迁飞性害虫之一。为了阐明影响稻纵卷叶螟在富宁大规模集中降落的关键天气学因子，通过HYSPLIT轨迹数值模拟平台、天气学背景分析软件GRADs，结合当地水稻生育期情况对富宁站2007年5月30日以及2009年5月21日出现的2次田间赶蛾高峰的迁入过程及虫源地进行个例分析。结果表明，2007年5月30日富宁田间出现的稻纵卷叶螟迁入种群直接来自越南红河三角洲，2009年5月21日富宁的迁入种群主要来自桂西南稻区；持续的偏南暖湿气流与降水是造成稻纵卷叶螟种群5月份在富宁大规模迁入和集中降落的关键因子。

Abstract: The rice leaf roller (Cnaphalocrocis medinalis) is a serious migratory pest on rice in the southeast  of Yunnan,China. In order to illustrate the largescale landing mechanism of population of C. medinalis, two immigration processes in Funing County on 30 May 2007 and on 21 May 2009 and the atmospheric backgrounds during the peak days were analyzed based on the data from field survey and by using HYSPLIT, a trajectory analysis software, GrADS (Grid Analysis and Display System).We got the following results: 1) The early immigration of C. medinalis in 2007 directly come from the Red River Delta of Vietnam, and the continuous south airflow and precipitation were the key meteorological factors to the mass landing of the moths; 2) The main source areas of the early immigration of C. medinalis in 2009 were  the southwest  of Guangxi Province. The continuous rainfall and strong south airflow were the key factors which affected the immigration process of C. medinalis.

Key words: Cnaphalocrocis medinalis, source areas, trajectory analysis, landing mechanism
