“We had a report that only about 60 moths were trapped in Napa this year, and most of those came from one property,” Bedwell said. “Two years ago, literally thousands of moths were being trapped there, and last year less than 200. We continue to make strides. It’s important to keep efforts up so this can be eradicated in Napa as well within a couple years.”
Soon after the moth was found in California, Mexico began requiring additional treatments on exports of fresh table grapes and stone fruit. Those restrictions have been lifted on counties declared free of the pest, according to the USDA.
Mexico is one of the top five export markets for U.S. table grapes and the third largest importer of U.S. fresh stone fruit. Last year, California exported 3.4 million cartons of fresh stone fruit, valued at $45 million, and 5.7 million boxes of fresh table grapes, worth $102.1 million, to Mexico.
Outreach, surveys, grower-led treatments and quarantine enforcements cost about $10 million annually since 2009.
