DOI: https://doi.org/10.1002/ps.6913 Interpretive Summary: Technical Abstract: Zebra Chip disease (ZC), associated with the plant pathogenic bacterium “Candidatus Liberibacter solanacearum” (psyllaurous) (CLso), is a major threat to global potato production. In addition to yield loss, CLso infection causes discoloration in the tubers rendering them unmarketable. CLso is transmitted by the potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae). ZC is managed by prophylactic insecticides applications to control the vector, which is costly and carries environmental and human health risks. Given the expense, difficulty, and unsustainability of managing vector-borne diseases with insecticides, screening and breeding efforts were undertaken to identify sources of resistance to CLso and develop varieties that are resistant or tolerant to CLso and/or potato psyllids. These efforts include field and laboratory evaluations of non-cultivated germplasm and cultivars, studies of tubers in cold storage, detailed quantifications of biochemical responses to infection with CLso, possible mechanisms underlying insect resistance, and traditional examination of potato quality following infections. This review provides a brief history of ZC and potato psyllid, provides a summary of currently available tools to manage ZC, and provides a comprehensive review of work on ZC and potato psyllids within the context of potato breeding and examines breeding within the greater context of IPM strategies. |
