G. d'A. aModelling the effect of an alternative host population on the spread of citrus Huanglongbing.h[electronic resource] c2013 aAbstract. The objective of this work was to model the spread of citrus Huanglongbing (HLB) considering the presence of a population of alternative hosts (Murraya paniculata). We developed a compartmental deterministic mathematical model for representing the dynamics of HLB disease in a citrus orchard, including delays in the latency and incubation phases of the disease in the plants and a delay period on the nymphal stage of Diaphorina citri, the insect vector of HLB in Brazil. The results of numerical simulations indicate that alternative hosts should not play a crucial role on HLB dynamics considering a typical scenario for the Recôncavo Baiano region in Brazil . Also, the current policy of removing symptomatic plants every three months should not be expected to significantly hinder HLB spread. aCitrus aGreening disease aMathematical models aModels aMurraya Paniculata aModelos matemáticos1 aTERNES, S.1 aLARANJEIRA, F.
