Abstract
The Mediterranean Oak Borer (Xyleborus monographus), an exotic invasive ambrosia beetle, has emerged as a significant threat to oak ecosystems in the Pacific Northwest. Currently limited to infestations in Oregon and California, X. monographus is associated with dieback and mortality in Quercus garryana (Oregon white oak) and Q. lobata (valley oak), ecologically and culturally significant species. Despite increasing evidence of its impact, X. monographus' behavior, population dynamics, and host interactions in its introduced range remain poorly understood. This research provides foundational insights into X. monographus in Q. garryana in Oregon. Preliminary observations reveal unique infestation patterns and potential risk factors, providing actionable insights for urban ecological management and invasive species mitigation in the Portland/Vancouver area and beyond.
