Abstract:Potential distribution of Corythucha ciliate ( Say) in China were predicted using two ecological niche modelling
algorithms ( i. e. ,MaxEnt and GARP) . The models were calibrated using domestic records and 6 bioclimatic variablesplus elevation. These potential distributions were then evaluated with respect to the distribution of pest host plant ( i. e. ,Platanus spp. ) . Significant variables associating with the bug’s occurrence were identified. Both models performed gooddiscriminability compared to random prediction. Result of GARP was a little conservative compared to MaxEnt. Highsuitable areas identified by theconsensus of two models including: southwestern and central Shandong,eastern and centralSichuan,Chongqing,central Shaanxi,eastern and central Henan,Anhui,Jiangsu,Shanghai,Guizhou,Hunan,Jiangxi,Zhejiang,northern and central Fujian,and central Yunnan. In addition,the central and southern Hebei,easternShandong,and northern Guangdong and Guangxi also showed high suitability. Significant variables inferred by MaxEntsuggest that the annual mean and extreme low temperature are two major factors that explain bug’s distribution.Considering the bug’s tolerance to hot and cold temperature,the south ( Nanning and Guangzhou) and north border(Dalian,Beijing,Shijiazhuang,Taiyuan) of Platanus acerifolia’s distribution should be monitored carefully as a result.
