Technical Abstract: The redbay ambrosia beetle, Xyleborus glabratus, is an exotic wood-boring pest first detected in the U.S. in 2002 near Savannah, Georgia. Females of X. glabratus vector a newly-described fungal pathogen (Raffaelea lauricola) that causes laurel wilt, a lethal disease of trees in the family Lauraceae. Laurel wilt has spread throughout the southeastern coastal plain, causing extensive mortality in native Persea species, including redbay (P. borbonia) and swampbay (P. palustris). Currently, it poses an imminent threat to commercial avocado (P. americana) in south Florida, and with continued westward spread, will threaten avocado production in Mexico and California as well. This presentation summarizes field and laboratory research focused on identification of the semiochemicals used by X. glabratus for host location. An understanding of host-based attractants will facilitate development of improved lures for early pest detection and control.
