    PC: Workers spray a vineyard in Rutherford to kill the eggs and larvae of the European grapevine moth. The moth has been found in Fresno, Mendocino, Sonoma and Solano, but the biggest infestation has been found in Napa county.

NAPA — California agricultural officials say they have successfully beaten back an invasive species that was threatening the state's wine industry.

Traps are now turning up only a handful of European grapevine moths. State Department of Food and Agriculture spokesman Steve Lyle tells the San Francisco Chronicle early in the year, officials were finding hundreds of moths per trap.

The invaders were first detected in Napa County in September 2009 after one grower lost his entire 9-acre vineyard.

They were later found in nine other counties, including Sonoma and Monterey.

Officials and growers responded with sticky traps, quarantines and insecticides.
