'Candidatus Liberibacter asiaticus' is transmitted by Diaphorina citri, an insect with a wide range of hosts in Rutaceae. Species related to Citrus occur in Brazilian forests where they may serve as hosts for psyllids and infested citrus orchards.
The suitability of plants as hosts of D. citri was classified into four groups. Group I (high suitability): Citrus × aurantium 'Valencia', 'Citrus limonia', Murraya paniculata (syn. Murraya exotica L.) (Aurantioideae: Aurantieae) and Bergera koenigii (Aurantioideae: Clauseneae). Group II (intermediate to low suitability): Citrus (Poncirus) trifoliata 'Pomeroy', Citrus wintersii, Swinglea glutinosa (Aurantieae) and Clausena lansium (Clauseneae). Group III (not suitable): Aegle marmelos, Atalantia buxifolia, Citrus ('Microcitrus') sp. (Aurantieae) and Helietta apiculata (Amyridoideae). Group IV (non-hosts): Glycosmis pentaphylla (Clauseneae), Balfourodendron riedelianum, Casimiroa edulis, Esenbeckia febrifuga, Esenbeckia leiocarpa, Metrodorea stipularis, Zanthoxylum rhoifolium (Amyridoideae) and Dictyoloma vandellianum (Cneoroideae). Insects survived longer on newly differentiated leaves compared with fully expanded soft leaves. Psyllids either did not develop or did not survive for long on most Group IV species, all of which, with the exception of G. pentaphylla, occur naturally in Brazilian forests.
Citrus relatives occurring in forests near citrus orchards are not suitable hosts of D. citri and, therefore, do not contribute to huanglongbing spread. © 2018 Society of Chemical Industry.
“亚洲韧皮杆菌”（Candidatus Liberibacter asiaticus）通过柑橘木虱（Diaphorina citri）传播，而柑橘木虱在芸香科中拥有广泛的宿主。与柑橘相关的物种存在于巴西森林中，它们可能是木虱和受感染柑橘果园的宿主。
将植物作为柑橘木虱宿主的适宜性分为四个等级。第一组（高适宜性）：甜橙‘瓦伦西亚’（Citrus × aurantium‘Valencia’）、酸橙（Citrus limonia）、金橘（Murraya paniculata）（芸香科：柑橘亚科）和飞龙掌血（Bergera koenigii）（芸香科：花椒亚科）。第二组（中低适宜性）：枳（Poncirus） trifoliata‘Pomeroy’、宜昌橙（Citrus wintersii）、密脉榕（Swinglea glutinosa）（柑橘亚科）和山黄皮（Clausena lansium）（花椒亚科）。第三组（不适宜）：酸木瓜（Aegle marmelos）、算盘子（Atalantia buxifolia）、小芸香（Citrus‘Microcitrus’）（柑橘亚科）和苦槛蓝（Helietta apiculata）（金虎尾科）。第四组（非宿主）：五桠果（Glycosmis pentaphylla）（花椒亚科）、伯乐树（Balfourodendron riedelianum）、余甘子（Casimiroa edulis）、九节（Esenbeckia febrifuga）、五指毛桃（Esenbeckia leiocarpa）、山小橘（Metrodorea stipularis）、两面针（Zanthoxylum rhoifolium）（金虎尾科）和黄皮树（Dictyoloma vandellianum）（芸香科）。与完全展开的软叶相比，昆虫在新分化的叶片上存活的时间更长。木虱要么不能发育，要么在大多数第四组物种上不能长时间存活，除了五桠果外，所有这些物种都自然存在于巴西森林中。
柑橘果园附近森林中出现的柑橘亲缘种不是柑橘木虱的适宜宿主，因此不会促进黄龙病的传播。 © 2018 化学学会。
