| temporal and spatial analysis of potato psyllid haplotypes in the united states. | the potato psyllid, bactericera cockerelli (sulc) (hemiptera: triozidae), is an economically important pest of potato (solanum tuberosum l.) crops across the western and central united states, as it is known to cause psyllid yellows disease and to transmit the bacterium that causes zebra chip disease. recent genotyping of b. cockerelli collected during the 2011 potato growing season identified three psyllid haplotypes within the western and central united states according to their geographical r ... | 2013 | 23575030 |
| arthropod pests and predators associated with bittersweet nightshade, a noncrop host of the potato psyllid (hemiptera: triozidae). | bittersweet nightshade (solanum dulcamara l.) is a key noncrop host of the potato psyllid (bactericera cockerelli šulc), proposed to be a source of the psyllids that colonize potato (solanum tuberosum l.) fields in the northwestern united states. here, we describe the broader community of arthropod potato pests, and also predatory arthropods, found in bittersweet nightshade patches. over 2 yr, we sampled arthropods in patches of this weed spanning the potato-growing region of eastern washington ... | 2016 | 27357162 |
| a potato model intercomparison across varying climates and productivity levels. | a potato crop multimodel assessment was conducted to quantify variation among models and evaluate responses to climate change. nine modeling groups simulated agronomic and climatic responses at low-input (chinoli, bolivia and gisozi, burundi)- and high-input (jyndevad, denmark and washington, united states) management sites. two calibration stages were explored, partial (p1), where experimental dry matter data were not provided, and full (p2). the median model ensemble response outperformed any ... | 2017 | 27387228 |
| seasonal population dynamics of three potato pests in washington state. | pest phenology models allow producers to anticipate pest outbreaks and deploy integrated pest management (ipm) strategies. phenology models are particularly useful for cropping systems with multiple economically damaging pests throughout a season. potato (solanum tuberosum l.) crops of washington state, usa, are attacked by many insect pests including the potato tuberworm (phthorimaea operculella zeller), the beet leafhopper (circulifer tenellus baker), and the green peach aphid (myzus persicae ... | 2016 | 27271946 |
