“…Genetically engineered potatoes could be a powerful tool to confer host plant resistance to the vector and/or pathogen, but public skepticism and marketing restrictions currently limit such applications. Recent technological advances in spectral imaging tools facilitate ZC monitoring in the field (30) or on tubers at harvest (46,60,154); further development of such technologies could aid in removing field inoculum and culling infected tubers after harvest. Artificial neural network classifiers can be used with spectral imaging as a tool in high-throughput potato screening, facilitating plant breeding efforts to detect sources of resistance to ZC (60).…”

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.

“…Above‐ground plant matter can be analyzed with PCR, as can sampled insects, but these methods require specialized equipment, making them difficult to implement at a mass scale. There are also detection methods for tubers preharvest, like spectral imaging of whole tubers 110,111 and image processing of cut tubers 112 …”

“…There are also detection methods for tubers preharvest, like spectral imaging of whole tubers 110,111 and image processing of cut tubers. 112 Standard insecticide programs targeting potato psyllids, at least in the USA and New Zealand, include at-plant application of a neonicotinoid insecticide. 2,[113][114][115] Because efficacy is expected to diminish by late season, when potato psyllids in many areas occur in greater abundance, [116][117][118][119][120] additional foliar applications are often used through the end of the growing season.…”

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.

“…Para evaluar el daño en el tubérculo mediante una escala, se siguió la metodología descrita por Hernández-Deheza et al (2020). Después de la cosecha se tomaron cinco tubérculos por tratamiento; cada uno se cortó por la mitad y de cada mitad se consideró una rebanada de 2 mm de grosor, para obtener 10 rebanadas de tubérculo por tratamiento.…”

Las variedades de papa (Solanum tuberosum L.) producidas en México son susceptibles a Candidatus Liberibacter solanacearum (CaLso), causante de la enfermedad conocida como ‘manchado interno de la pulpa’, por lo que se requiere conocer la respuesta de genotipos experimentales a la bacteria. El presente estudio tuvo como objetivo evaluar el efecto de la infección de los haplotipos LsoA + LsoB de CaLso en el follaje, la biomasa seca y la calidad de tubérculo de papa, variedad Fianna, una colecta de Solanum demissum y los clones experimentales T90-1-63 y T05-13-21 de Solanum spp. El manchado interno de la pulpa del tubérculo se determinó mediante análisis de imágenes de tubérculos. Las plantas de Fianna mostraron la mayor severidad de daño foliar; en cambio, los clones experimentales presentaron 17 % menos daño foliar que Fianna y 8 % más daño foliar que S. demissum. Este último fue el genotipo con la mayor biomasa seca de hoja y produjo tubérculos de un tamaño pequeño; las plantas infectadas de S. demissum presentaron mayor número de tubérculos y mayor rendimiento de tubérculo fresco que las plantas sin inoculación, aunque tuvieron la menor proporción de superficie sana del tubérculo. El clon T90-1-63 presentó los porcentajes más altos de superficie sana de tubérculo (> 79 %) y las menores intensidades del manchado interno de la pulpa del tubérculo.
