滇东南富宁稻纵卷叶螟的迁入过程与虫源地分析
Analysis on the Immigration Process and Source Population of the Rice Leaf Roller (Cnaphalocrocis medinalis Guenee)at Funing County in Southeast of Yunnan Province,China
摘要
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 .关键词
