Mediterranean Fruit Fly

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."

In the Mexican state of Colima, a recent outbreak of the Mediterranean fruit fly, also known as medfly, was very bad news. This voracious pest was eradicated in Mexico in the 1980s with the help of FAO and the International Atomic Energy Agency (IAEA), but insects know no borders. And unfortunately, with climate change, increase of trade and global travel favouring the spread of pests, they have once more found their way into this horticulturally important state, threatening to wreak havoc on the industry and on the livelihoods of farmers. Thankfully, Mexico, FAO and the IAEA had prepared for just a scenario.

The Medfly is one of the world’s most destructive pests, attacking over 200 fruits and vegetables. In June 1980, it was discovered in two highly populated urban areas in the Santa Clara Valley of northern California. APHIS and the California Department of Food and Agriculture (CDFA) began eradication activities within days. However, the overall eradication program lasted more than 27 months—and APHIS and CDFA needed to adjust and adapt their methods along the way to achieve success.
