SACRAMENTO, August 30, 2018 – A portion of Sacramento and Yolo Counties have been placed under quarantine for the Oriental fruit fly following the detection of 15 flies in and around the southern part of the City of Sacramento near the Lemon Hill community. The quarantine zone measures 123 square miles, generally bordered on the north by El Camino Avenue; on the south by Laguna Boulevard; on the west by the Sacramento River; and on the east by Bradshaw Road. A link to the quarantine map may be found here: https://www.cdfa.ca.gov/plant/off/regulation.html.
Following the principles of Integrated Pest Management (IPM), CDFA primarily uses the “male attractant” technique to eradicate this pest. Trained workers squirt a small patch of fly attractant mixed with a very small dose of pesticide approximately 10 feet off the ground on street trees and similar surfaces; male fruit flies are attracted to the mixture and perish after consuming it. This approach has successfully eliminated dozens of fruit fly infestations from California over the last several decades.
The Oriental fruit fly is known to target over 230 different fruit, vegetable, and plant commodities. Damage occurs when the female fruit fly lays her eggs inside the fruit. The eggs hatch into maggots and tunnel through the flesh of the fruit, making it unfit for consumption.
While fruit flies and other invasive species that threaten California’s crops and natural environment are sometimes detected in agricultural areas, the vast majority are found in urban and suburban communities. The most common pathway for these pests to enter the state is by “hitchhiking” in fruits and vegetables brought back illegally by travelers when they return from infested regions of the world or ship infested produce through the mail.
