Citrus Greening and Asian Citrus Psyllid (ACP)
Citrus greening, one of the most significant citrus diseases, was first detected in Florida in 2005. The disease is now distributed throughout Florida and portions of South Carolina, Louisiana, Georgia, and Puerto Rico. Citrus greening is spread by the Asian citrus psyllid (ACP), its insect vector. ACP is widely dispersed in the United States, including Texas, Louisiana, Mississippi, Alabama, Georgia, Florida, Hawaii, and the Territories of Puerto Rico and Guam, as well as areas of Southern California and Arizona.
