(Sept. 2, 9:30 a.m.) The pest that can transmit citrus greening apparently has been trapped near San Diego, the first time it has been discovered in California.

In an Aug. 29 news release, the California Department of Food and Agriculture said the specimen, thought to be the Asian psyllid, was being air freighted to the U.S. Department of Agriculture’s entomological laboratory in Washington, D.C. to positively identify the insect, and whether it is a carrier of citrus greening.

“The Asian psyllid is a dangerous pest of citrus,” said California Agriculture Secretary A.G. Kawamura in the news release. “We must move quickly to identify the full extent of the infestation and do all we can to protect our state’s citrus industry.”

State inspectors spent the holiday weekend setting and checking traps and conducting visual surveys in the area where the insect was found in an attempt to detect additional Asian psyllids. The insect was trapped approximately 11 miles north of the international border with Mexico, according to the news release.

If the specimen is found to be an Asian psyllid, it will trigger an immediate quarantine. Until the entomological laboratory relays its findings to California officials, the state agency will restrict movement of host plants at wholesale and retail nurseries in a five mile radius around the trap where the insect was discovered, the news release said.

California’s vast citrus industry went on alert in late June when the international division of the Department of Agriculture detected three Asian psyllids in traps in Tijuana, Baja California. Within a week, the total of Asian psyllids trapped in the Mexican city climbed to nearly 140.

To date, none of the psyllids trapped in Mexico has been found to be a citrus greening carrier.
