A pest known as a threat to grapevines has been found in a residential area of Vacaville and state and local agricultural officials are continuing to survey the area to determine the next steps to eradicate the infestation.
At least five glassy-winged sharpshooters were detected earlier this month via traps set broadly around parts of the state, and additional traps set up in the same area afterward detected about 35 more of the insects, according to the California Department of Food and Agriculture.
Glassy-winged sharpshooters pose a threat to grapevines because they can spread a bacterium that causes Pierce’s disease, which is incurable and kills grapevines within two to five years of infection, state agricultural officials said.
The insect is native to the southeastern U.S. and northeastern Mexico but can currently be found in 12 counties in California. The infestation in Vacaville is the only known one currently north of the Madera area in the Central Valley.
State and Solano County officials are informing local growers and other members of the community of the infestation and are working to determine if pesticide treatments will be necessary in the area, which hasn’t had a detection of the pest since 2004.
If pesticide treatments are done, it would be via ground equipment to properties with host plants within a 150-meter radius of each detection site, and residents of the affected properties would be invited to a meeting with state and local officials and be notified at least 48 hours in advance of any treatment, according to the California Department of Food and Agriculture.
