Disposition of Cucurbitacin as a Factor in Host Plant Selection by Diabroticite Beetles and Electrophoretic Analysis of the Coevolved Genus Cucurbita
Five species of Diabroticites with different host plant affinities produced an essentially identical array of metabolites when fed radio-labeled cucurbitacin B. All species excreted the bulk of the cucurbitacin (67.17-94.59% total dpm); permanently sequestered a small proportion of a cucurbitacin D …

Bean Leaf Beetle: Impact of Leaf Feeding Injury on Snap Beans, Host Plant Choice and Role as a Vector of Bean Pod Mottle Virus in Virginia
… BLB. In the manual-defoliation study, snap bean plants had significant yield loss when > 25% of leaf area was removed. In the field cage experiments, I was unable to establish beetle densities per plant to impact yield. Host plant selection by BLB was done in laboratory and field studies with …
