Bactrocera dorsalis (Oriental Fruit Fly) - APHIS Establishes New Regulated Area in Los Angeles, California

Country: United States

Title: Bactrocera dorsalis (Oriental Fruit Fly) - APHIS Establishes New Regulated Area in Los Angeles, California

John Stewart, National Fruit Fly Policy Manager, at 919-855-7426


Effective August 9, 2017, the Animal and Plant Health Inspection Service (APHIS), the California Department of Food and Agriculture (CDFA), and the Los Angeles County Agricultural Commissioner established a new oriental fruit fly (Bactrocera dorsalis or OFF) regulated area in the city of Los Angeles, California.

Between August 1 - 9, 2017, APHIS and CDFA confirmed the detection of eight adult OFF in Los Angeles, California. The eighth detection triggered the establishment of the new OFF quarantine, which encompasses approximately 75 square miles of Los Angeles, California. APHIS is applying safeguarding measures and restrictions on the interstate movement of regulated articles from this area. This OFF outbreak is considered transient, actionable, and under eradication.

APHIS is working with CDFA and the Agricultural Commissioner of Los Angeles County to respond to these detections following program survey and treatment protocols. This action is necessary to prevent the spread of OFF to non-infested areas of the United States. The establishment of this regulated area is reflected on the following designated website, which contains a description of all the current Federal fruit fly regulated areas:

Under IPPC Standards, Bactrocera dorsalis is considered to be a pest that is transient, actionable, and under eradication in the United States.
