Abstract

2026–2029 Florida Citrus Production Guide (Citrus Production Fundamentals). The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, was first detected in Florida in 1998, and it has since become the key pest of citrus due to its role as vector of the pathogen that causes citrus greening disease, also known as huanglongbing (HLB) detected in 2005. The HLB pathogen, Candidatus Liberibacter asiaticus (CLas), is transmitted and spread by adult ACP but acquired primarily by nymphs. ACP are sucking insects, related to aphids, that obtain most of their nutrition from phloem sap, which they access by feeding on leaves.
