Risk analysis of the establishment of Scaphoideus titanus, vector of “flavescence dorée” phytoplasma in grapevine, under current and estimated climate change conditions in Chile

Abstract

Chile is free of the “flavescence doree” disease and its vector Scaphoideus titanus. Given the importance of viticulture industry in the country, it is fundamental to know which could be the consequences in case of accidental insect introduction in the Country. The potential distribution of the vector was evaluated through a model using the BIOCLIM-DOMAIN tool, considering the current climatic conditions and the projections of estimated climate change in Chile. Results indicated that the establishment and the survival of the insect in Chile is possible considering current and projected climatic conditions.
