We analyzed the distribution of the origins and migration pathways of white⁃backed planthoppers (WBPHs), Sogatella furcifera (Hemiptera; Insecta), in Sichuan, China. The WBPHs were collected daily from light traps at seventeen stations between May and July, 2012. The trajectories and distributions of the source areas during the peak days of WBPH migration were simulated and analyzed using HYSPLITY4.8 (Hybrid Single⁃Particle Lagrangian Integrated Trajectory) and ArcGIS. Additionally, the meteorological backgrounds of the WBPH immigration peak source areas were analyzed using Grads (Grid Analysis and Display System). During the early migratory stage (May⁃June), S. furcifera congregated in the southern and eastern areas of Sichuan. WBPHs from south Sichuan traveled to northern Vietnam and Laos, and to the southeast and northeast of Yunnan Meanwhile,WBPHs sourced from the eastern parts of Sichuan were found south of Chongqing, west of Hu′ nan, and at the border junction of Hu′ nan, Hubei, and Chongqing (which partly extends into
