Differences in p red iction p erfo rmance of the three models with th reshold s were observed. An evaluation using independen t reco rd s of D. bivittatus showed that Maxen t offers the most accurate p red ictions than two o ther models based on three values of ROC /AUC, Kappa, and TSS. Pred iction ou tcomes made by Maxen t revealed that the th ree fruit fly sp ecies have b road ly similar poten tial ranges in Central Am erican, South American, Sou theast A sia, and Coastal areas of Au stralia in general. D. cilia tus has the comparatively widest potential range among the th ree sp ecies, includ ing Coastal areas ofM e
