中文摘要：白背飞虱是贵州省水稻重要迁飞害虫，近年来发生严重。为了明确贵州白背飞虱的来源地，本文根据2011年贵州省荔波、天柱、望谟、惠水、从江、锦屏6个代表站点的虫情资料，采用HYSPLIT轨迹分析平台进行虫峰回推轨迹分析，结果表明：（1）2011年贵州虫峰于5月中上旬迁入，迁入高峰期多集中在6月份；（2）2011年贵州地区早期白背飞虱虫源地为主要为越南红河三角洲，广西中南部，桂东南与广东交界；该研究结果为进一步明确我国喀斯特地区白背飞虱的虫源地和迁飞路线提供参考。
英文摘要：Sogatella furcifera (Horváth) is an important migratory pest on rice in Guizhou，resulted in serious damage in recent years. In order to define the source aeras of early immigrant white-backed planthoppers (WBPH) in Guizhou, the analysis of push-back trajectory of white-backed planthoppers was conducted by HYSPLIT，a trajectory analysis software for the simulation of migration pathways，and light trap catch data from six survey station of Guizhou, including Libo, Tianzhu, Wangmo, Huishui, Congjiang and Jinping in 2011. The results showed that: (1) In Guizhou in 2011, peaks of white-backed planthoppers immigrated in beginning and middle of May, the peak period of immigration were concentrated in June; (2) The source aera of the early immigration population of white-backed planthoppers of Guizhou in 2011 were from Red River Delta of Vietnam, south-central of Guangxi, Southeast of Guangxi and Guangdong border; the results of the research provided a reference for further exploration of source regions and migratory routes of WBPH in Karst region of China.
