Asian Citrus Psyllid
The Asian citrus psyllid threatens America's citrus. Don't risk citrus, don't move citrus.
The Asian Citrus Psyllid (Diaphorina citri Kuwayama or ACP) causes serious damage to citrus plants and citrus plant relatives. Burned tips and twisted leaves result from an infestation on new growth. Psyllids are also carriers of the bacterium that causes Huanglongbing (HLB) disease, also known as citrus greening disease, spreading the disease to healthy citrus plants. Citrus greening is one of the most serious citrus plant diseases in the world. Once a tree is infected, there is no cure.

What You Can Do
Know the quarantines in your area and learn to leave Hungry Pests behind.
Consult Federal and State websites for specific information and regulations. Contact the USDA Cooperative Extension Service in your area for further information.
Citrus plants sold in a regulated state must be sold from a certified vendor and be accompanied by a USDA certificate.
Commercial citrus businesses, internet shippers and roadside vendors within regulated states should be able to prove they are in compliance with the federal quarantine. Before you buy, ask the vendor if their product is in compliance.
The movement of branches, cut greens, green waste, dead trees and other regulated items will be regulated and enforced by federal, state and county quarantine officials.
Cut flower producers in quarantined areas are not affected unless they utilize Murraya, a host plant closely related to citrus, or flowers and branches cut from plants regulated for citrus greening and Asian citrus psyllid.
Within quarantine areas consume home-grown citrus fruit at home and do not transport home-grown citrus or citrus plants out of the area.
