Asian Citrus Psyllid Marches North In California Citrus Belt
January 22, 2015 | A portion of Fresno County along its border with Tulare County has been placed under quarantine for the Asian citrus psyllid (ACP) following the detection of three ACP in one trap in the unincorporated area between the City of Dinuba and Delft Colony.The quarantine expansion into Fresno County measures approximately 30 square miles; all of Tulare County remains under quarantine as a result of previous ACP detections.
The quarantine area in Fresno County is bordered on the north by E. Lincoln Avenue; on the south by the Fresno County boundary line; on the west by E. Manning Avenue; and on the east by the Fresno County boundary line. The quarantine prohibits the movement of citrus and tree nursery stock out of the quarantine area and requires that all citrus fruit be free from ACP prior to moving out of the quarantine area. An exception may be made for nursery stock and budwood grown in USDA-approved structures which are designed to keep ACP and other insects out. Residents with backyard citrus trees in the quarantine area are asked not to transport citrus fruit or leaves, or potted citrus trees from the quarantine area. ACP county-wide quarantines are now in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare, and Ventura counties, with portions of Fresno, Kern, Madera, San Joaquin, San Luis Obispo, and Santa Clara counties also 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 disease. There is no cure once a tree becomes infected, the diseased tree will decline in health and produce bitter, misshaped fruit 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 ACP or symptoms of HLB on their citrus trees are urged to call CDFA’s Invasive Species Hotline at 1-800-491-1899. Here’s more information on ACP and HLB. Source: California Department of Food and Agriculture |
