Abstract
Tomato (Lycopersicum esculentum) crops grown in several departments of Honduras and heavily infested with the psyllid Bactericera cockerelli were observed in April of 2012 with plant symptoms suggestive of “Candidatus Liberibacter solanacearum” infection. B. cockerelli is a serious pest of potato, tomato, and other solanaceous plants and a vector of “Ca. L. solanacearum” (1,2,3,4). The symptoms included overall chlorosis, severe stunting, leaf cupping, excessive branching of axillary shoots, an
