The goldspotted oak borer (GSOB), Agrilus auroguttatus Schaeffer, is an invasive wood-borer associated with tree mortality in San Diego County, California since 2008, and is believed to have been introduced via infested firewood from southeastern Arizona. From 2011-2013, I recorded GSOB emergence holes on Quercus agrifolia trees at eight locations within San Diego County. I evaluated the effectiveness of crown class and purple prism traps as tools to monitor GSOB populations. I also identified possible tree and site characteristics that could explain the variation in GSOB population densities. Crown class was useful in monitoring GSOB populations unlike purple prism traps. Larger trees (>50 cm diameter at breast height), trees located near a stand's edge, and trees previously infested had the greatest emergence hole densities. Sites closer to GSOB's putative original point of infestation and those with an intermediate Q. agrifolia density (30-50 trees per hectare) had greatest infestation levels.
