The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) announced the European grapevine moth (EGVM) (Lobesia botrana) has been eradicated from California and is lifting the Federal quarantine on 446 square miles of Napa and Sonoma Counties that have been under regulation since June 2010. APHIS and the California Department of Food and Agriculture (CDFA) have conducted extensive survey, control, and regulatory efforts for over three years and found no EGVM in this last quarantined area. This means the United States is free from this pest and unrestricted movement of grapes and other host commodities from these areas can resume. This action is effective on August 18, 2016.

In October 2009, APHIS confirmed the first detection of EGVM in the United States in major grape production areas of Northern California. In 2010, APHIS took regulatory actions and established quarantine boundaries, ultimately detecting nearly 101,000 moths that year. APHIS partnered with CDFA and affected counties to work closely with industry, the University of California Cooperative Extension Service, the EGVM Technical Working Group, and other stakeholders to eradicate this pest within California.

The grape industry along with the state, county, university, and Federal cooperators will remain vigilant by continuing to monitor for EGVM and other economic grape pests. Learn more about EGVM and other invasive pests
