Maximum entropy (MaxEnt) modeling was used to predict impact of climate change on habitat
suitability of guava fruit fly, Bactrocera correcta in India. It is a polyphagus pest on a wide variety of fruit
crops. Future prediction of potential habitat of B.correcta was done for the year 2050 and 2070 with RCP
2.6, RCP 4.5, RCP 6.0 and RCP 8.5 climate scenarios. The model preformed better than random with an
average test AUC value of 0.75 of 100 replicate tests run. Under the present and future climatic conditions,
the model predicted high habitat suitable category for B. correcta in the areas of south-western coastal
(Kerala, Karnataka, Tamilnadu, Maharashtra and Gujarat) part of India by 2050 and 2070. Presently
absolute unsuitable areas of Indian sub-continent are projected to be slightly suitable for B. correcta by
2070 due to increase in temperature coupled with decrease in cold stress. The predictive modeling
approach presented here provides an outline for future risk of B.correcta in India under climate change
scenarios, which can be used for its better management strategies.
