Invasive moth numbers dwindle in Calif. vineyards

California agricultural officials say they have 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 that early in the year, there were 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.

Growers responded with sticky traps, quarantines and insecticides.

Lyle says $8 million has been spent so far on treatment and fruit removal in California.
