“…While foliar symptoms caused by CLso may resemble other potato diseases and disorders, 7,8 the typical brown discoloration of vascular rings and medullary rays in the tuber tissue are distinctive of ZC 93 . The brown stripes are likely caused by an accumulation of polyphenol oxidases and phenolic compounds in infected tubers 87,104–106 which primes the tubers to quickly turn brown on exposure to air 98,107,108 .…”

“…The above‐ground symptoms of CLso infection typically appear 3–4 weeks after pathogen inoculation, beginning with curling and yellowing/purpling of the developing leaves 91 . Stunted growth, reduced internodes, aerial tubers, and dwarfing are subsequent symptoms 3,7,8,46,92,93 . These symptoms are predominantly caused by altered host physiology, including changes in compositions of amino acids and reducing sugars, and induction of plant defenses.…”

“…Foliar symptoms include leaf‐scorch, upward rolling of leaves, and formation of aerial tubers 6 . However, the most characteristic symptom of ZC is the necrotic flecking and brown discoloration of tubers that result in a ‘zebra stripe’ pattern, rendering the affected tuber unmarketable 6–8 . This symptom is more pronounced when the tuber slices are fried.…”

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 insecticide 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, identifying sources of resistance to CLso and developing varieties that are resistant or tolerant to CLso and/or potato psyllids has become a major goal of breeding efforts. These efforts include field and laboratory evaluations of noncultivated 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, a summary of currently available tools to manage ZC, and a comprehensive review of breeding efforts for ZC and potato psyllid management within the greater context of Integrated Pest Management (IPM) strategies. © 2022 Society of Chemical Industry.

The potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae), transmits the pathogen “ Candidatus liberibacter solanacearum” (Lso), the putative causal agent of zebra chip disease (ZC). ZC is a disease of potato that reduces yield and quality and has disrupted integrated pest management programs in parts of the Americas and New Zealand. Advances in our understanding of the ecological factors that influence ZC epidemiology have been accelerated by the relatively recent identification of Lso and motivated by the steady increase in ZC distribution and the potential for devastating economic losses on a global scale. Management of ZC remains heavily reliant upon insecticides, which is not sustainable from the standpoint of insecticide resistance, nontarget effects on natural enemies, and regulations that may limit such tools. This review synthesizes the literature on potato psyllids and ZC, outlining recent progress, identifying knowledge gaps, and proposing avenues for further research on this important pathosystem of potatoes. Expected final online publication date for the Annual Review of Entomology, Volume 69 is January 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
