7. Confirmation of bean leaf beetle, Cerotoma trifurcata, feeding on cucurbits
The objective of these studies was to assess the degree to which bean leaf beetle, Cerotoma trifurcata (Forster), will feed on cucurbits. In 2003, we documented an infestation of C. trifurcata in a commercial pumpkin field near Rosemount, MN, USA. To evaluate C. trifurcata feeding on cucurbits, we conducted laboratory no-choice and choice test feeding studie

12. Molds on vegetables at the time of harvest.
The mean numbers of colony-forming units of molds present on vegetables at the time of harvest were in the range of 4.2 X 10(3) to 6.7 X 10(3)/g for all vegetables except cucurbits and asparagus. The numbers were not influenced by cultivars within species, duration of the growing season, distant separation of the growing fields, or elevation above ground. Nu
