Las is the most aggressive, widespread, and most studied of these pathogens. Las) in the United States, Brazil, and Asia. Lam) in South America, and ‘ Candidatus Liberibacter asiaticus’ ( C. Laf) in Africa and some parts of Asia, ‘ Candidatus Liberibacter americanus’ ( C. HLB has since been associated with ‘ Candidatus Liberibacter africanus’ ( C. In the 1960s, HLB was thought to be caused by Citrus tristeza virus. The first probable record of HLB was 260 years ago in India, where growers reported citrus ‘dieback’ in the 18th century. Huanglongbing (HLB) is the most serious disease of citrus and is causing economic devastation in Florida. within the current and historical context of another fastidious emergent plant pathogen, future basic and applied research to develop control strategies can be prioritized.
By placing the study of Candidatus Liberibacter spp. fastidiosa and their potential applicability to the liberibacters associated with citrus greening, with a focus on the interactions between bacterial pathogen and insect vector. Our review highlights the successful strategies used to understand and control X. Proactive quarantine and vector control measures coupled with interdisciplinary data-driven science established control of this devastating disease and pushed the frontiers of knowledge in the plant pathology and vector biology fields. However, scientists and grape growers were once in a comparable situation after the emergence of Pierce’s disease, which is caused by Xylella fastidiosa and spread by its hemipteran insect vector. Bacteria in the genus cannot be cultured and no durable strategy is available for growers to control plant infection or pathogen transmission. Huanglongbing is causing economic devastation to the citrus industry in Florida, and threatens the industry everywhere the bacterial pathogens in the Candidatus Liberibacter genus and their insect vectors are found.
