    Abstract:
    BACKGROUND: The coconut hispine beetle Brontispa longissima Gestro (Coleoptera: Chrysomelidae) is one of the most serious pests of the coconut palm, Cocos nucifera L. (Arecales: Arecaceae) and other palms. The invasion of B. longissima causes major economic and ecological losses worldwide. In this study, the impacts of climate change on the risk of spread were evaluated. CLIMEX was used to project its global potential distribution based on historical climate data (1987-2016) and simulated future climate data (2071-2100). RESULTS: The distribution of B. longissima included each continent under historical and future climate conditions. However, climate suitability was predicted to decrease in most tropical and subtropical regions under a climate change scenario. Temperature was a more important determinant of the climatic suitability of the pest than relative humidity or precipitation. The availability of host plants (Arecaceae) only had a slight impact on climate suitability in some regions. CONCLUSION: The projected potential distribution of B. longissima will help to determine the impacts of climate change and will provide supportive information for the development of management strategies to reduce future economic and ecological losses. © 2019 Society of Chemical Industry.
