Farm Compliance

The quarantine measures 82 square miles and is bordered on the west by an imaginary line that intersects Copus Rd. halfway between Highway 99 and I-5; on the south by Legray Rd.; on the east by an imaginary line in the foothills between Rancho Rd. and Herring Rd; and on the north by an imaginary line extending from Kenmar Ln. Additional information about this quarantine, including a map, is available at: http://www.cdfa.ca.gov/phpps/PE/InteriorExclusion/melonff_quarantine.html

The movement of host fruits and plants grown in the quarantine areas is restricted. Residents living within the boundaries are asked not to move host plants and materials from their property.

"We don't see the melon fruit fly in California as often as some as some other pests, but it is still very damaging," said CDFA Secretary A.G. Kawamura. "This quarantine allows us to protect surrounding uninfested areas by preventing movement of the fruit fly."

While fruit flies and other pests threaten California's crops, the vast majority of them are detected in urban and suburban areas.  The most common pathway for these pests to enter the state is by "hitchhiking" in fruits and vegetables brought back illegally by travelers as they return from infested regions around the world.

The melon fly is native to Asia. The melon fly occurs in Africa, Sri Lanka, China, Guam, India, New Guinea, Taiwan, Rota, the Ryukyu Islands, Thailand and much of Southeast Asia. In the United States, its distribution is limited to the Hawaiian Islands.  The larvae of the melon fly have been recorded in over 100 different hosts worldwide. It is a particularly serious pest of melon and cucumber-type crops.
