Over the past several years, the Asian citrus psyllid (ACP), a serious invasive pest, has established a population in California and presents a major threat to the California citrus industry. The psyllid serves as a vector for huanglongbing, or citrus greening disease, which has no cure and eventually kills any tree it infects.

IGIS has been working with Dr. Beth Grafton-Cardwell (Extension Specialist, Entomology, UC Riverside) on an online mapping application to monitor the spread of ACP and provide information to commercial citrus growers and the public about managing the pest. In addition to a map of current distribution of the psylid and quarantine zones, the site provides background on both the pest and the disease as well as treatment options and cost estimates.
