European grapevine mothCourtesy University of California Statewide IPM ProgramLarvae of European grapevine moths feed on the fruit and blossoms of grapevines.The California Department of Food and Agriculture has lifted the European grapevine moth quarantine in four counties: Santa Clara, Nevada, Santa Cruz and part of Sonoma County.

The actions affect about 317,000 acres, according to a news release.

But the quarantine remains in effect for all of Napa County as well as parts of Sonoma and Solano counties, an area of about 439,000 acres.

The European grapevine moth, known scientifically as Lobesia botrana, was first found in the United States in Napa County, Calif., vineyards in 2009.

Endemic to Europe, the Mediterranean, the Middle East, Africa, Chile, Japan and southern Russia, the larvae of the pest feeds on the flowers and fruit of grapevines, and the flowers of olives and rosemary, according to a CDFA informational pamphlet.

At the peak of the infestation, much of California's grape-growing region from Fresno County north was under a European grapevine moth quarantine.
