Genome-scale phylogeography resolves the native population structure of the Asian longhorned beetle, (Motschulsky).

Human-assisted movement has allowed the Asian longhorned beetle (ALB, (Motschulsky)) to spread beyond its native range and become a globally regulated invasive pest. Within its native range of China and the Korean peninsula, human-mediated dispersal has also caused cryptic translocation of insects, resulting in population structure complexity. Previous studies used genetic methods to detangle this complexity but were unable to clearly delimit native populations which is needed to develop downstream biosurveillance tools.

Hybridization Potential of Two Invasive Asian Longhorn Beetles.

The Asian longhorned beetle (ALB), (Motschulsky) and citrus longhorned beetle (CLB), (Förster) (both Coleoptera: Cerambycidae: Lamiinae), are high-risk invasive pests that attack various healthy hardwood trees. These two species share some similar host plants and overlapping distributions in large parts of their native ranges in China and the Korean peninsula as well as similar reproductive behaviors. The original (Thomson) occurs in Japan and has been synonymized as CLB (hereafter referred to JCLB).
