More trees infested with goldspotted oak borer

When GSOB emerges from underneath bark, they leave "D"-shaped exit holes.
Two more trees in Idyllwild are infested with goldspotted oak borer, reported the Riverside Press-Enterprise yesterday. The announcement came at a community meeting over the weekend, in which Tom Scott, UC Cooperative Extension specialist in the Department of Natural Resources at UC Riverside, and Kevin Turner, UC Cooperative Extension goldspotted oak borer program coordinator, joined fire and forestry officials to brief local residents about the new pest threat in the area.

Residents learned how to examine oak firewood this winter and how watch their black oaks and coast live oaks this spring for signs that they may harbor the insect. Firewood or trees suspected of being infested should be reported to (951) 659-3850, the story said. More information is available at the UC Cooperative Extension GSOB website.

Officials enlist mountain residents to battle goldspotted oak borer

Cal Fire, UC Cooperative Extension and other officials will be meeting with residents of Idyllwild tomorrow to enlist their help in stopping the goldspotted oak borers' tree destruction in the picturesque mountain community, reported the Riverside Press-Enterprise.

GSOB appears to have spread to Idyllwild by hitchhiking on firewood from San Diego, where it has killed some 80,000 oak trees. It has been found in only one tree in Idyllwild so far.

Tom Scott, UC Cooperative Extension specialist in the Department of Environmental Sciences at UC Riverside, and Kevin Turner, UCCE goldspotted oak borer program coordinator, will be among the speakers.

Meanwhile, ABC Eyewitness News in Los Angeles interviewed UC Riverside entomologist Vanessa Lopez about an effort to bring in GSOB predators to California from Arizona.

"What we're hoping to do is go to Arizona and find those insects that are specialized to only feed on goldspotted oak borer and they're efficient at controlling the population," Lopez said.
