Interpretive Summary:

Technical Abstract: Bactericera maculipennis is a native psyllid that commonly occurs on field bindweed in the western United States. We have found that Pacific Northwest populations of B. maculipennis carry Liberibacter solanacearum, the pathogen associated with zebra chip disease of potato. In North America, this pathogen is primarily associated with the potato psyllid, Bactericera cockerelli. Although potato psyllid prefers host plants within the Solanaceae, this insect can also develop on field bindweed. Our results suggest that interspecific transmission of Liberibacter has occurred between B. maculipennis and potato psyllid on host plants shared by these two psyllid species. Potato is not a host for B. maculipennis, and potato plants exposed to Liberibacter-infected B. maculipennis did not acquire Liberibacter. We therefore conclude that B. maculipennis is not a direct threat to potato despite its ability to carry the zebra chip pathogen.
