Basic information about Asian citrus psyllid, including identifying the insect, monitoring and management.

UC Agriculture and Natural Resources is working with the citrus industry and the state to wage an all-out battle against the Asian citrus psyllid (the insect) and huanglongbing (the disease it spreads) that are threatening California’s citrus. This tiny insect and disease have already destroyed one-third of the citrus in Florida, at a cost of over $200 million a year, and both have recently been detected in California.
