“Liberibacter solanacearum”
IntroductionThe potato psyllid Bactericera cockerelli is the insect vector of the fastidious bacterium ‘Candidatus Liberibacter solanacearum’. The bacterium infects both B. cockerelli and plant species, causing zebra chip (ZC) disease of potato and vein-greening disease of tomato. Temperatures are known to influence the initiation and progression of disease symptom in the host plant, and seasonal transitions from moderate to high temperatures trigger psyllid dispersal migration to facilitate sur
