Potential geographical distribution model of Solenopsis invicta Buren in China.

Based on the main climatic critical factors of the distribution of Solenopsis invicta Buren,effective accumulative temperature and biological climate similar distance,Access Database,MapInfo MapX and Visual Basic design process were selected to build a geographical distribution model of S.invicta.Using 670 sites meteorological climate data(30 years) to run the model,the predicting results showed S.invicta existed in 65.82% regions of our country,and the potential geographical distribution could be divided into security area,mild dangerous area,dangerous area and high-risk areas,in which dangerous area and high-risk area accounted for 37.91%.
