Oriental Fruit Flies Found in Los Altos Hills, Eradication Program to Commence July 10th

SANTA CLARA COUNTY, CALIF. – An infestation of Oriental Fruit Fly was discovered in the Town of Los Altos Hills and the City of Los Altos.  Two flies were trapped in a residential neighborhood northeast of the intersection of Highway 280 and El Monte Avenue.  The identification of these insects was confirmed by the California Department of Food and Agriculture (CDFA).  According to State protocol, the trapping of two 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 Friday, July 10, 2015 and will involve the male attractant technique (MAT) using ground-based, spot applications of insecticide and pheromone lure.  This mixture is applied as small, dollar-sized spots (“bait stations”) on street trees and utility poles at a height of eight to ten 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 14 square miles as part of this eradication effort.  The treatment area is roughly bounded by Alma Street to the north, Miramonte Avenue on the east, Ravensbury Avenue on the south, and La Cresta Drive to 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 known to attack 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.
