基于MaxEnt模型的烟粉虱(Bemisia tabaci)全球适生区预测OA

Bemisia tabaci is a complex of several genetically distinct cryptic species,and as a globally invasive pest,its infestation poses a serious threat to crop yields and economic returns.In this study,we predicted the potential global distribution of Bemisia tabaci under current climatic conditions using the MaxEnt model.Model evaluation showed that the area under the curve(ROC-AUC)of the working characteristics of the subjects reached 0.915;significance analyses indicated that the mean temperature of coldest quarter(BIO11),isothermality(BIO3)and the precipitation of wettest month(BIO13)were the dominant environmental factors.The prediction of suitable areas showed that the non-suitable areas for Bemisia tabaci accounted for 71.68%of the global land area,and the suitable areas together accounted for 28.32%,of which the low,medium and highly suitable areas accounted for 13.24%,10.75%and 4.33%respectively.The highly suitable areas were concentrat-ed in the tropical and subtropical regions near the equator.The present study has elucidated the differences in the response of Bemisia tabaci populations to climate change and their geographical distribution pattern,which provides a basis for the prevention and control of Bemisia taba-ci damage,as well as a reference framework for the management of other invasive species.
