Asian Citrus Psyllid (ACP) and Huanglongbing (HLB)

ACP

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.

More information and presentations given at the ACP Workshop for Citrus Growers, Nursery Operators and PCAs sponsored by the Ventura County ACP-HLB Task Force are available here.  For a list of resources on ACP and HLB, link to our More ACP Information webpage (also listed on the left).

If you suspect ACP infestation in Ventura County:

Report it immediately to the CDFA hotline at 800-491-1899, or contact the Ventura County Agricultural Commissioner at 805-933-2926. 

Other counties, please contact the above CDFA hotline number or your local county agricultural commissioner's office.
