Asian Citrus Psyllid Quarantine Declared In Coastal California County

A portion of southern San Luis Obispo County has been placed under quarantine for the Asian citrus psyllid (ACP) following the detection of one psyllid in the Arroyo Grande area.

The quarantine zone measures 84 square miles, bordered on the north by Corbett Canyon Road; on the south by Oso Flaco Lake Road; on the east by Mehlscau Creek; and on the west by the coast of California. Here’s a link to the quarantine map.

The quarantine prohibits the movement of citrus and curry tree nursery stock out of the quarantine area and requires that all citrus fruit be cleaned of leaves and stems prior to moving out of the area. An exception may be made for nursery stock and budwood grown in USDA-approved structures designed to keep ACP out. Residents with backyard citrus trees in the quarantine area are asked not to transport fruit, citrus or curry leaves, or potted trees from the quarantine area.

In addition to San Luis Obispo County, ACP quarantines are now in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Ventura and portions of Fresno, Kern, and Tulare Counties. A total of more than 46,420 square miles are under quarantine.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species, such as curry trees, are susceptible hosts for both the insect and the disease. There is no cure once a tree becomes infected. The diseased tree will decline in health until it dies. HLB has been detected just once in California – in 2012 on a single residential property in Hacienda Heights, Los Angeles County. This plant disease does not affect human health.

Residents in the area who think they may have seen the Asian citrus psyllid are urged to call CDFA’s Pest Hotline at 1-800-491-1899. Here’s more information on the Asian citrus psyllid and huanglongbing disease.
