Federal and state agriculture officials in late September established Oriental fruit fly (OFF) quarantines in Sacramento, San Bernardino and Riverside counties in California. The actions were taken by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA APHIS) and the California Department of Food and Agriculture (CDFA) following OFF detections in those areas.
The new quarantines come on the heels of the recent OFF quarantines established in portions of California’s Contra Costa and Santa Clara counties.
SACRAMENTO COUNTY
The Sacramento County quarantine was established in response to the confirmed detections of eight adult male OFF from various sites in the cities of Sacramento and Rancho Cordova by CDFA between Sept. 12 and Sept. 17. CDFA confirmed one additional male OFF from Rancho Cordova on Sept. 19 and one unmated female OFF from Sacramento on Sept. 20. All were from traps in various types of trees in residential areas.
This quarantine area encompasses 105.9 square miles of Sacramento County. There is no commercial agriculture in the quarantine area.
SAN BERNARDINO AND RIVERSIDE COUNTIES
The San Bernardino and Riverside quarantine was established in response to the confirmed detections of six adult male OFF from various sites in the city of Redlands, San Bernardino County, by CDFA between Sept. 18 and Sept. 21. Between Sept. 22 and Sept. 27, CDFA confirmed 111 additional male and one mated female adult OFF in the Redlands area. All were from traps in various types of trees in residential areas. Additionally, on Sept. 26, CDFA confirmed 43 OFF larvae from citrus fruit at one residential site within the quarantine area.
The quarantine area encompasses 102 square miles of San Bernardino County and the adjacent Riverside County. There are approximately 1,200 acres of commercial agricultural production — including citrus, apples, avocados, peaches and other stone fruit — in this quarantine area.
The establishment of these quarantine areas is reflected on the APHIS fruit fly website, which contains a description of all current federal fruit fly quarantine areas.
Additional information on the OFF quarantine areas is available from APHIS Fruit Fly National Policy Manager Richard Johnson at 301-851-2109 or richard.n.johnson@usda.gov.
