The article describes how the presence of the Asian Citrus Psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Liviidae), in parts of Africa, most recently trapped in southwestern Tanzania and Kenya, is increasing the risk to citriculture in Southern Africa. ACP is an effective vector of Huanglongbing (HLB), which is a destructive citrus greening disease and is associated with the gram negative α-Proteobacteria Candidatus Liberibacter asiaticus (Las).
