What is the Goldspotted Oak Borer?

Adult GSOB
Goldspotted oak borer (GSOB) Agrilus auroguttatus is an invasive pest contributing to the on-going oak tree mortality occurring on federal, state, private, and local Native American lands in San Diego County. In Fall 2012, GSOB-infestated trees were identified in a mountain community in Riverside County. Widespread oak mortality can have severe implications to the environment and human safety. Due to the current and potential impacts to California oaks and communities, public and private organizations are working together in the research, education and outreach efforts related to GSOB pest management.
