Bactericera
psyllid bugs, jumping plant lice
Bactericera is a genus of psyllid bugs (family Triozidae) established by Auguste Puton in 1876. The genus is predominantly distributed in the Palaearctic and Nearctic regions, with 24 recognized species in North America north of Mexico. Members are small phloem-feeding insects commonly known as "jumping plant lice." The genus includes economically significant agricultural pests, most notably Bactericera cockerelli (potato/tomato psyllid), which transmits the bacterial pathogen 'Candidatus Liberibacter solanacearum' causing zebra chip disease in potatoes.
Bactericera cockerelli
potato psyllid, tomato psyllid, tomato/potato psyllid
Bactericera cockerelli, commonly known as the potato psyllid or tomato psyllid, is a phloem-feeding insect native to southern North America. It is a major agricultural pest of solanaceous crops, particularly potatoes and tomatoes, causing direct feeding damage and transmitting the bacterium Candidatus Liberibacter solanacearum, which causes zebra chip disease in potatoes and psyllid yellows in other hosts. The species has expanded its range northward and has been introduced to New Zealand, where it causes significant economic damage to protected and outdoor crops.
Bactericera maculipennis
psyllid, jumping plant louse
Bactericera maculipennis is a psyllid species in the family Triozidae, native to western North America. It is a confirmed vector of 'Candidatus' Liberibacter solanacearum, the bacterium that causes zebra chip disease in potatoes. The species develops primarily on plants in the Convolvulaceae family, with field records documenting association with Convolvulus arvensis (field bindweed) throughout the western United States. Unlike the related potato psyllid B. cockerelli, B. maculipennis has not been documented as a direct economic threat to solanaceous crops, though it shares pathogen reservoirs with that species.
