Prediction of potential geographic distribution areas for three mango weevils in China using GARP modeling system

Sternochetus Pierce is a major pest on mango. It's very important for monitoring and controlling these pests of define the high suitable probability areas of them. An ecological niche modeling method ( the Genetic Algorithm for Rule - set Prediction, GARP) was applied to predict potential geographic distribution of three species of mango weevil in China on this paper, such as S. mangiferae, S. olivieri, S. frigidus base of the data about current distribution area of three species and 14 environmental and geological covariates in Asia. The resulting GARP geographic predictions were exported as ASCII raster grid - files into ArcGIS 9. 0 for further analysis prediction of the potential distribution of S. mangiferae, S. olivieri, S. frigidus in China. The results indicated that the three mango weevils have strong tendency for spreading and dangerous for mango cultivation in China.
