Identification, treatment and control of the Asian citrus psyllid


The Asian citrus psyllid (ACP) is a dangerous pest that has proven itself deadly to commercial citrus groves and residential trees. The pest vectors a disease called Huanglongbing (also known as citrus greening), which makes citrus fruit bitter and misshapen. There is currently no cure for the disease.

There are several useful websites to gather additional information on the pest:

Residents who think they may have ACP's in their citrus trees, or have questions, can contact their county agricultural commissioner's office or similar local agency to report a pest and get more information. Residents can contact the CDFA Toll-Free Pest Hotline at 1-800-491-1899 to report suspicious insects or disease symptoms in citrus trees.

There is even a smart phone app available on the CDFA website that California residents can download and use to report a pest.
