The Asian citrus psyllid ACP is a pest that acts as a carrier or vector spreading "huanglongbing" HLB , a devastating disease of citrus trees. This bacterial disease is transmitted to healthy trees by the psyllid after it feeds on infected plant tissue. Photo Credit: Jeffrey W.

CNS — State agricultural inspectors have detected bacteria which can cause a disease deadly to citrus trees during routine pest trapping in Fallbrook, San Diego County officials announced Thursday. The bacteria, which is not harmful to people or animals, was detected on insects in the North County community. These bacteria can cause a citrus disease called Huanglongbing. At this time, the disease has not been detected in citrus trees in San Diego County.

The entire county is included in the quarantine zone. The ACP is an invasive species of concern because it can carry the disease huanglongbing HLB , also known as citrus greening. All citrus and closely related species, such as curry leaf trees, are susceptible hosts for both the insect and disease. There is no cure once the tree becomes infected. A diseased tree will decline in health and produce bitter, misshaped fruit until it dies.
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. 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. 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.
