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.
