In response to the recent detection of the European grapevine moth (EGVM) in Napa County, the California Department of Food and Agriculture (CDFA) has established a quarantine of 162 square miles including portions of Napa, Sonoma and Solano counties.
The detection of an EGVM larva in a trap in the Oakville area on Sept. 15, 2009, was the first detection of this pest in the United States. Confirmation of that detection led to increased trapping and surveys that have since detected the pest at several sites, generally contained in two pockets of infestation: one on the eastern side of the City of Napa and the other between Oakville, Rutherford and St. Helena. Maps of the two quarantine zones and additional information are available at www.cdfa.ca.gov/PHPPS/PE/InteriorExclusion/egvm_quarantine.html.
"Grapes are our state's top crop," said CDFA Secretary A.G. Kawamura. "This quarantine will help us ensure that the infestation doesn't have an opportunity to spread. I fully understand that quarantines impact both the public and our growers. It is important and necessary to protect our food supply and the larger environment from these invasive pests, so the entire community's cooperation is essential and appreciated."
