Bactrocera dorsalis (Oriental Fruit Fly), Quarantine areas in California-Orange County

Country: United States

Title: Bactrocera dorsalis (Oriental Fruit Fly), Quarantine areas in California-Orange County

Not available


On February 16, 2003, APHIS published an Interim rule (7 CFR 301.93) in the Federal Register for Oriental Fruit Fly (OFF). This rule regulates the artificial spread of this plant pest from moving out of the areas where the pest is established. We have now learned that a county not yet under quarantine has been found to have several detections of OFF. The pest was first detected, confirmed and reported to us by the California Department of Agriculture from a residential area of Santa Ana, Orange County on June 28, 2004. A total of nine male and two unmated female OFF detections were confirmed in the area. The last detection was on July 2, 2004. 

Therefore, effective immediately, we are imposing a temporary designation of quarantine in this residential area. 

This action is authorized by the Plant Protection Act of June 20, 2002, Section 412(a) which authorizes the Secretary of Agriculture to prohibit or restrict the movement in interstate commerce of any plant, plant part, or article if the Secretary determines the prohibition or restriction is necessary to prevent the dissemination of a plant pest within the United States. This action is also authorized by 7 CFR 301.93-3(b) which authorizes temporary designation while we proceed toward publishing a rule to add the areas to the list of quarantined areas listed in 7 CFR 301.93-3(c). 

Ten square miles of this residential area will be treated using the male annihilation technique. Male annihilation bait treatments consist of applying methyl eugenol, Naled, and a thickener to 600 evenly-spaced bait stations (trees, telephone poles) per square mile. Treatments will be repeated at two-week intervals for two lifecycles beyond the last fly find. 

This action will be reflected in an interim rule that we anticipate will soon be published in the Federal Register for public comment in accordance with the provisions of the Administrative Procedures Act.
