The objectives of this study were to: (i) document oviposition preferences on a range of tomato cultivars; (ii) determine threshold levels for psyllid densities that would cause psyllid yellows on tomatoes within the first three weeks following transplanting; and (iii) identify the most important \u2018psyllid yellows\u2019 symptoms that might be used in surveying and monitoring for this pest. Plant lines tested included the commonly-planted commercial cultivars \u2018Shady Lady\u2019 and \u2018QualiT 21\u2019, an older, previously commercial cultivar \u20187718 VFN\u2019, a common cultivar planted by consumers \u2018Yellow Pear\u2019, and a wild type plant accession, PI 134417. When given a choice, psyllids significantly preferred \u2018Yellow Pear\u2019 and avoided PI 134417 for oviposition. Under no-choice conditions psyllids laid significantly fewer eggs on PI 134417, but all the other plant lines were equally good substrates for laying eggs. Thus, oviposition preference is not likely to provide a functional management strategy in large plantings. On \u2018Shady Lady\u2019, psyllids preferred to oviposit on plants already infested with adults. On both \u2018Shady Lady\u2019 and \u20187718 VFN\u2019 oviposition was significantly greater on plants previously infested by nymphs as compared to uninfested control plants. This suggests that, at least for some cultivars, there is a physiological change in plant attractiveness following psyllid feeding. \u2018Yellow Pear\u2019 and \u2018QualiT 21\u2019 were relatively tolerant of psyllids, requiring 18 nymphs per plant to produce the disease symptoms. Only eight nymphs per plant were needed on \u2018Shady Lady\u2019 and \u20187718 VFN\u2019. For all cultivars, the pest density showed strong correlations with measurements such as the number of yellowing leaves and leaflets and distorted leaves, which were as good as or better than the first factor extracted from principal component analysis. Therefore, such measurements have the potential to simplify field surveys.<\/jats:p>","DOI":"10.1079\/ber2005416","type":"journal-article","created":{"date-parts":[[2006,3,18]],"date-time":"2006-03-18T15:56:38Z","timestamp":1142697398000},"page":"197-204","source":"Crossref","is-referenced-by-count":33,"title":["Ovipositional preferences, damage thresholds, and detection of the tomato\u2013potato psyllid <i>Bactericera cockerelli<\/i> (Homoptera: Psyllidae) on selected tomato accessions"],"prefix":"10.1017","volume":"96","author":[{"given":"D.","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.T.","family":"Trumble","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,3,9]]},"reference":[{"key":"S000748530600023X_ref026","doi-asserted-by":"publisher","DOI":"10.1017\/S0006323198005271"},{"key":"S000748530600023X_ref004","unstructured":"Carter R.D.
