[Aim] To estimate the potential risk of Spodoptera frugiperda to corn and other crops in China and other parts of the world.[Method] In this study, we integrated moderate-resolution imaging spectroradiometer (MODIS) based maize planting data with ensemble ecological niche model forecast of S. frugiperda potential distribution to estimate the risk.[Result] We found that intensively corn planting areas were covered by high suitable areas of S. frugiperda that estimated by ensemble models across the globe, pest control programs should thus be enforced in these corn planting areas, where monitoring and scouting programs should be taken in non-corn planting areas. In China, spring corn are planted in North China Plain and summer corn in Huanghuai Plain, they all fell into high suitable areas of S. frugiperda, intensive corn planning area in southwestern China and in three provinces of the northeastern China have medium risk, where corn planting in mountain areas in southern China and irrigated corn in northwestern China have low risk. Different efforts should target on these areas accordingly as they showed different risk of infest. In the non-intensive corn planting areas in southern and southeastern China, the potential of S. frugiperda infest on non-corn crops (e.g. rice and bean) should be carefully monitored, as these areas have high suitability values.[Conclusion] Integration S. frugiperda potential distribution from ensemble forecast with the host plant corn planting lead us a better knowledge of their distributions, which will benefit risk analysis and pest management.
