Asian Citrus Psyllid

The Asian citrus psyllid is a small insect that feeds on the leaves and stems of citrus trees. The insect is extremely dangerous because it can transmit a disease, Huanglongbing, that is fatal for citrus. In August 2008, Asian citrus psyllia was found in Ventura County.

The California Department of Food and Agriculture has implemented multiple strategies to deal with the pest including mandatory eradication, treatments, containment, and release of predatory wasps. A monitoring/detection system is in place for Asian citrus psyllid using sticky traps located in host plants to help detect any possible infestations as well. Destruction of Huanglongbing infected plants is the current method of eradication for Huanglongbing.
