Goldspotted Oak Borer in Southern California


The goldspotted oak borer (GSOB) Agrilus coxalis (Coleoptera: Buprestidae), is a wood borer native to southeastern Arizona, southern Mexico, and northern Guatemala. It is believed to be introduced into California and was first collected in San Diego County in 2004. In 2008, GSOB was linked to continuing oak mortality occurring in San Diego County since 2002 across all land ownerships. It is now also found in Orange, Los Angeles, Riverside and San Bernardino Counties.
