The Huanglongbing (HLB) disease pyramid is composed of Liberibacters, psyllid vectors, citrus hosts, and the environment. The epidemiological outcomes for Liberibacter-associated plant diseases are collectively determined by the inherent relationships among plant-Liberibacters-psyllids, and how various environmental factors affect plant-Liberibacter-psyllid interactions. Citrus-Liberibacter-psyllid interactions occur in a complex microbiome system. In this review, we focus on the progress in understanding the HLB disease pyramid, and how the microbiome affects the HLB disease pyramid including the interaction between HLB and the citrus microbiome; the interaction between Liberibacters and psyllids; the interaction between Liberibacters and gut microbiota in psyllids; and the effect of HLB on selected above- and belowground citrus pathogens. Their implications for HLB management are also discussed.
黄龙病（HLB）病害三角由韧皮部杆菌、木虱传播媒介、柑橘寄主和环境组成。与韧皮部杆菌相关的植物病害的流行病学结果是由植物-韧皮部杆菌-木虱之间的内在关系以及各种环境因素如何影响植物-韧皮部杆菌-木虱相互作用共同决定的。柑橘-韧皮部杆菌-木虱相互作用发生在一个复杂的微生物群落系统中。在这篇综述中，我们重点关注在理解HLB病害三角方面取得的进展，以及微生物群落如何影响HLB病害三角，包括HLB与柑橘微生物群落之间的相互作用；韧皮部杆菌与木虱之间的相互作用；韧皮部杆菌与木虱肠道微生物群之间的相互作用；以及HLB对选定的地上和地下柑橘病原体的影响。还讨论了它们对HLB管理的意义。
