Oriental Fruit Flies Found in Santa Clara County, Eradication Program to Commence June 26th

​SANTA CLARA COUNTY, CA. – An infestation of Oriental Fruit Fly was discovered in the City of Cupertino.  Six flies were trapped in a residential neighborhood west of the intersection of Highway 85 and De Anza Boulevard.  The identification of these insects was confirmed by the California Department of Food and Agriculture (CDFA).  According to State protocol, the trapping of six flies resulted in an emergency proclamation by the California Secretary of Agriculture authorizing immediate implementation of an eradication program.
The planned eradication program is scheduled to commence June 26, 2015, and will involve the male attractant technique (MAT) using ground-based, spot applications of insecticide and pheromone lure.  This gelatinous mixture is applied as small, dollar-sized spots (“bait stations”) on street trees and utility poles at a height of six to eight feet that are typically inaccessible and cause minimal disruption to the public.  The male fruit flies are attracted to these spots because of the lure, and die from feeding on the minute amount of insecticide in the mixture.
CDFA workers will treat an area of approximately 15 square miles as part of this eradication effort.  The treatment area is roughly bounded by E. Homestead Road to the north, Stevens Canyon Road on the east, Pierce Road on the south, and Johnson Avenue on the west.   Each treatment will take 2 to 3 days to complete and will be repeated every two weeks for approximately 8 weeks. 
Oriental Fruit Fly is an exotic insect pest found throughout much of southern Asia.  Distribution in the United States is restricted to the Hawaiian Islands.  Oriental Fruit Fly is a pest of over 230 kinds of fruits and vegetables including citrus, stone fruits, apple, pear fruits, avocado and tomato.  Female flies lay egg inside fruits and vegetables.  Once maggots develop and feed on the pulp, the fruit will decay and fall to the ground. 
Infestations of Oriental Fruit Fly likely result from the introduction of contraband fruit. 
Photo and Interview Opportunity with the Commissioner: A State crew will be applying bait station lures at the cross streets of S. Stelling Road near Waterford Drive and Aster Lane in Cupertino at 9:00 A.M. on June 26, 2015.
