Submitted to: Meeting Proceedings
Publication Type: Proceedings Publication Acceptance Date: 4/30/2018 Publication Date: N/A Citation: N/A Interpretive Summary: A major challenge in controlling zebra chip disease of potatoes is our inability to predict what potato fields are likely to be colonized by potato psyllid, the vector of the pathogen that causes zebra chip. Researchers at the USDA-ARS laboratory in Wapato, WA developed a novel method to identify what host plants the psyllids previously fed upon. This tool allows the researchers track the migratory history of captured psyllids and to identify the plant sources of psyllids arriving in potato fields. This information will help researchers and growers predict psyllid pressure from year-to-year and to develop a more targeted approach to controlling potato psyllid and zebra chip disease.
