Asian longhorned beetle (Anoplophora glabripennis – ALB), is a native forest pest in China and the Korean peninsula. This species has successfully invaded and spread to hardwood forests in North America and Europe. ALB mines the heartwood of a range of tree species and poses a significant threat to invaded forest ecosystems. Tracking and responding to the ALB invasion requires knowledge of its native population structure and rapid response to new infestations. We used genomic approaches to characterize its native population structure and trace the North American invasion. Our results showed clear population differences between ALB populations in China and South Korea, with at least two distinct sources of invasion present in North America. These results provide much greater clarity to the invasive history of the North American ALB populations and sets foundation for mapping the global invasive history of ALB.
