Abstract Huanglongbing (HLB) or "greening" is currently considered the most serious citrus disease in Brazil and worldwide, whose symptoms are associated with the bacteria "Candidatus Liberibacter spp.". Since there are no curative measures for the disease, the management is based on preventive measures such as the control of the insect vector Diaphorina citri. This insect has a host range including more than 50 species of the family Rutaceae, especially those of the genus Citrus, although it cannot complete its development on all of them. Such hosts may play an important role in the spread of the disease because it allows the psyllid to survive on these plants in the absence of more suitable hosts. Although a large number of studies report the differential development of D. citri on different host species (mainly citrus), little is known about the influence of native rutaceous species on the bioecological parameters of D. citri. Thus, the objective of this work is to evaluate 9 native species of the family Rutaceae as potential hosts for D. citri aiming to provide subsidies for vector management. (AU) | |
