Oriental Fruit Fly Detected in Anaheim Area of Orange County

A map of the treatment area is available at: http://www.cdfa.ca.gov/phpps/PDEP/treatment/treatment_maps.html

Treatment of the Oriental fruit fly primarily relies upon a process known as “male attractant” in which workers squirt a small patch of fly attractant mixed with a very small dose of pesticide approximately 8-10 feet off the ground to street trees and similar surfaces. Male flies are attracted to the mixture and die after consuming it. On and near the properties where the flies were found, crews will also remove and dispose of host fruits and vegetables from yards and gardens and apply treatments to plants using the organic-approved substance spinosad.

Agricultural officials have increased the number of insect traps in the region to help determine the extent of the infestation. Once that work has been completed, a quarantine boundary will be set and a map posted online.

With the infestation in Anaheim, California now has seven active OFF eradication projects underway. The others include two in Los Angeles County (the San Gabriel/Alhambra area and the Baldwin Park area); two in Orange County (the Anaheim/Yorba Linda area and the Santa Ana/Westminster area); one in San Joaquin County in the Stockton area, where a quarantine was declared on September 21; and one in the Pleasanton area of Alameda County, where two OFF adults were recently detected in traps.

To prevent the spread of fruit flies through homegrown fruits and vegetables, residents of fruit fly quarantine areas are urged not to move any fruits or vegetables from their property. Fruits and vegetables may be consumed or processed (i.e. juiced, frozen, cooked, or ground in the garbage disposal) at the property where they are picked.

To help prevent infestations, officials ask that residents do not bring or mail fresh fruit, vegetables, plants or soil into California unless agricultural inspectors have cleared the shipment beforehand, as fruit flies and other pests can hide in a variety of produce. It is important to cooperate with any quarantine restrictions and to allow authorized agricultural workers access to your property to inspect fruit and Oriental fruit fly traps for signs of an infestation.

The Oriental fruit fly is known to target over 230 different fruit, vegetable and plant commodities. Damage occurs when the female lays eggs inside the fruit. The eggs hatch into maggots that tunnel through the flesh of the fruit, making it unfit for consumption.

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 Oriental fruit fly is widespread throughout much of the mainland of Southern Asia and neighboring islands including Sri Lanka and Taiwan. It is also found in Hawaii.
