ABSTRACT A new huanglongbing (HLB) “ Candidatus Liberibacter” species is genetically characterized, and the bacterium is designated “ Candidatus Liberibacter psyllaurous.” This bacterium infects the psyllid Bactericera cockerelli and its solanaceous host plants potato and tomato, potentially resulting in “psyllid yellowing.” Host plant-dependent HLB transmission and variation in psyllid infection frequencies are found.
