Biology and host associations of redbay ambrosia beetle (Coleoptera: Curculionidae: Scolytinae), exotic vector of laurel wilt killing redbay trees

The redbay ambrosia beetle and its fungal symbiont, Rafaelea sp., are new introductions to the southeastern United States responsible for the wilt of mature redbay, Persea borbonia (L) Spreng., trees. In 2006 and 2007, we investigated the seasonal flight activity of X. glubratus, its host associations, and population levels at eight locations in South Carolina and Georgia where infestations ranged from very recent to at least several years old.
