a binomial sequential sampling plan for bactericera cockerelli (hemiptera: triozidae) in solanum lycopersicum (solanales: solanacea).the tomato-potato psyllid bactericera cockerelli (sulc) (hemiptera: triozidae) is a pest of many solanaceous plants, including tomato (solanum lycopersicum l.) and potato (solanum tuberosum l.). in tomato, feeding by nymphs is associated with "psyllid yellows." b. cockerelli also vectors "candidatus liberibacter psyllaurous," an infectious bacterium that causes "vein greening" disease. decisions about management action are much more effective when guided by robust sampling. however, there are fe ...201424772568
agricultural dust production in standard and conservation tillage systems in the san joaquin valley.the negative health effects of repeated dust exposure have been well documented. in california's san joaquin valley, agricultural operations may contribute substantially to airborne particulates. we evaluated four management systems to assess impacts on dust production and soil properties for a cotton (gossypium hirsutum l.)-tomato (lycopersicon esculentum mill.) rotation: standard tillage with (stcc) and without (stno) cover crop, and conservation tillage with (ctcc) and without (ctno) cover cr ...200615998847
identification and impact of natural enemies of bactericera cockerelli (hemiptera: triozidae) in southern california.bactericera cockerelli (sulc) (hemiptera: triozidae) is a major pest of potato, (solanum tuberosum l.), tomato (solanum lycopersicum l.), and peppers (capsicum spp.). the purpose of our research was to identify and determine the impact of natural enemies on b. cockerelli population dynamics. through 2 yr of field studies (2009-2010) at four different sites and laboratory feeding tests, we identified minute pirate bug, orius tristicolor (white) (hemiptera: anthocoridae); western bigeyed bug, geoc ...201223156144
no evidence of adverse effects on germination, emergence, and fruit yield due to space exposure of tomato seeds.seeds of 'rutgers california supreme' tomato (lycopersicon esculentum mill.) were exposed to outer space conditions aboard the long duration exposure facility (ldef) satellite in the space exposed experiment developed for students (seeds) project of the national aeronautics and space administration (nasa). seeds aboard the ldef were packed in dacron bags forming four layers per sealed canister. some of these seeds were used in oklahoma and florida for studies of germination, emergence, and fruit ...199611539352
