Mexican Fruit Fly

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has released Fruit Fly Exclusion and Detection Program Fiscal Years 2024-2028 Strategy [PDF, 1.2 MB]. APHIS worked with members of the National Plant Board to develop a unified roadmap for USDA and its partners to protect American agriculture from the threat of invasive fruit flies and measure our progress along the way.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS), and the California Department of Food and Agriculture (CDFA) in collaboration with County Agricultural Commissioners, are proud to announce that after a year of hard work we have eradicated all populations of invasive fruit flies from California. This significant achievement is a testament to the hard work of our agencies and the critical support from the public. 

USDA's Animal and Plant Health Inspection Service (APHIS) is using emergency funding to respond to the threats associated with growing outbreaks of exotic fruit flies and New World screwworm. U.S. Secretary of Agriculture Tom Vilsack approved the transfer of $213.3 million from the Commodity Credit Corporation to APHIS to directly support emergency response efforts domestically and internationally to protect fruit, vegetable and livestock industries and producers.

"Increasing our response efforts to exotic fruit fly and New World screwworm outbreaks is critical to minimizing their potential impact on our nation’s agriculture and trade," said USDA Under Secretary for Marketing and Regulatory Programs Jenny Lester Moffitt. "This funding will enable us to swiftly prevent both populations’ further spread before they become established and harder to eradicate."

A portion of San Diego County has been placed under quarantine for the Mexican fruit fly following the detection of six flies and one larva in and around the unincorporated area of Valley Center. The United States Department of Agriculture (USDA), the San Diego County Agricultural Commissioner, and the California Department of Food and Agriculture (CDFA) are working collaboratively on this project.

The Mexican fruit fly can lay its eggs in and infest more than 50 types of fruits and vegetables, severely impacting California agricultural exports and backyard gardens alike. For more information on the pest, please see the pest profile at: www.cdfa.ca.gov/plant/go/MexFly. Residents who believe their fruits and vegetables may be infested with fruit fly larvae are encouraged to call the state’s toll-free Pest Hotline at 1-800-491-1899.
