Aggregation behavior of adult western spotted cucumber beetles (Diabrotica undecimpunctata undecimpunctata Mannerheim) (Coleoptera: Chrysomelidae) was examined in six snap bean (Phaseolus vulgaris) fields adjacent to corn fields in western Oregon in 2004-2006. In the 2004 and 2005 studies, sweep net sampling was used to estimate beetle numbers along transect lines running perpendicular to the e...

Snap bean, a warm-season crop, have low frost tolerance. The optimal temperature for seed emergence and plant growth is important. Therefore, appropriate planting dates adapted varieties has paramount significance in improving pod yield quality of snap bean under short cool season climates. Three cultivars planted at 3 different were examined to evaluate the effects on traits 2-year study clima...

Cucumber mosaic virus (CMV) is a tripartite, positive-sense RNA plant virus in the genus Cucumovirus, family Bromoviridae. This virus is one of the most economically important viruses affecting several crop plant species and it has one of the widest host ranges among the characterized viruses. Recently, snap bean (Phaseolus vulgaris L.) and pepper (Capsicum annuum L.) crops in Wisconsin have ex...

Sugars, including fructose, glucose, and sucrose, contribute signifi cantly to the fl avor and consumer acceptance of snap beans (Phaseolus vulgaris L.). Differences between dry and snap bean cultivars and among snap bean cultivars in the patterns of accumulation of sugars have been observed. In ‘Eagle’, a white-seeded, largesieve snap bean cultivar, fructose and glucose concentrations in devel...
