Climate change effects on the global distribution and range shifts of citrus longhorned beetle Anoplophora chinensis
Journal of Applied Entomology 146 (5), 473-485
Abstract: The citrus longhorned beetle (CLB) (Anoplophora chinensis) is an important quarantine pest of main Citrus crops. Its potential distribution and invasion under climate change scenarios have important economic implications for many countries. We used the ensemble maps from both the CLIMEX and MaxEnt models to obtain CLB's potential distribution in climate-suitable regions under historical and future climate conditions. Global broadleaved forest cover was overlaid with CLB's ensemble distributions to further assess the effects of host range. The ensemble models' projected climate-suitable regions by 2040–2060 and 2060–2070 under different emission scenarios were used to analyze range shifts. Our results indicate that projected climate-suitable regions of the CLIMEX are much wider than that of the MaxEnt, but both of them would lose areas with climate change. The global ensemble distributions of CLB concentrated in eastern Asia, central and western Europe and eastern North America, and would shift northward in the future time. Broadleaved forests would cover most of the projected climate-suitable regions, which provide essential hosts for CLB's establishment. The ensemble predictive results from the correlative model and mechanistic model highlight the necessity of increasing control, monitoring and quarantine efforts on the pest in the threatened areas.
