Asian Citrus Psyllid (Diaphorina citri) - Regulated Area expanded in San Luis Obispo County in California

Country: United States

Title: Asian Citrus Psyllid (Diaphorina citri) - Regulated Area expanded in San Luis Obispo County in California

Citrus Health Response Program National Coordinator Prakash Hebbar at 301-851-2228 or National Policy Manager for Citrus Disease Programs Lynn Evans-Goldner at 301-851-2286.


Effectively immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture (CDFA), is expanding the area regulated for the Asian citrus psyllid (ACP) in California. APHIS is adding 158 square miles to the quarantined area due to additional detections of ACP in San Luis Obispo County.

APHIS is applying safeguarding measures on the interstate movement of regulated articles from the regulated area in San Luis Obispo County. These measures parallel the intrastate quarantine that CDFA enacted on August 26, 2014. This action is necessary to prevent the spread of ACP to non-infested areas of the United States. ACP is considered present only in some areas in California and is subject to official control via state and federal quarantines.

The specific changes to the regulated areas in California can be found at:

APHIS will publish a notice of this change in the Federal Register.

Under IPPC Standards, Asian Citrus Psyllid (Diaphorina citri) is considered to be a pest that is present, only in some areas, and subject to official control to limit its spread in the United States.
