Anoplophora glabripennis, the Asian longhorned beetle (ALB), is a serious pest of hardwood trees in China, North America and Europe. It is native to China and the Korean Peninsula and was introduced to North America and Europe. ALB control relies on removal of infested and susceptible trees. Host location, mating behaviors and associated semiochemicals are being elucidated for the purpose of developing attractant lures in support of ALB management (see pages 355–71). Here, a male ALB guards a female on a poplar tree in Ningxia, China. Photo provided by Dr. Jacob D. Wickham.
