【Background】Lissorhoptrus oryzophilus Kuschel (rice water weevil), an invasive exotic species to China, causes serious economic losses to the local agriculture. 【Method】Data on rice water weevil distribution were collected between 1996 and 2008 in Fujian, using GIS, Geodatabase, and ActiveX as MapObjects 2.0 and used to develop an information system with, which was based on Visual Basic 6.0 language. 【Result】The system included the functions of data of damaging uploading, management, searching and drawing of theme. The drawing of theme and scalability were the two main characteristics of the system. A suitable plant epidemic reporting system could be generated so as to provide epidemic reporting and GIS inquiry service for the prevention and control of agricultural pests and diseases without professional GIS and computer knowledge. 【Conclusion and significance】The system provides software management tools for realtime monitoring, prevention and control of rice water weevil. This system has a friendly interface, which will improve rice water weevil pest control.
