The Prediction of Potential Geographical Distribution of Seed Chalcids, Megastigmus likiangensis Roques et Sun
Abstract：To estimate scientifically the risk of this species and take effective measures, it＇s necessary to investigate the infected region and potential distribution of the species in Yunnan. Ecological niche model technique, Maxent, was used to predict potential distribution of the seed chacids, Megastigmus likiangensis Roques et Sun in Yunnan based on associations between known occrrence records and a set of environment variables： The highly suitable areas for Megastigmus likiangensis Roques et Sun in Yunnan province mainly in Lijiang district, included Yongsheng county, Yulong county, Huaping county, Ninglang county. The moderate suitable areas included Weixi county of Diqing district, Northern Dali county, Dayao county of Chuxiong, Yongren county, Yuanmou county, Dongchuan district of Kunming city. The low suitable areas included Kunming city, western Nujiang district, Baoshan city, Northern Lincang city, Jingdong district of Pu＇er city, Most of the areas in Qujing city and Honghe district. In addition to these areas, the rest of the regions were unsuitable areas for Megastigmus likian- gensis Roques et Sun. The AUC（Area Under roc curve） of the training data and the test data are respective 0. 995 and 1. 000, indicating that the Maxent had statistical significance for predicting the potential geographical distribution.
