Cross-Resistance And Resistance Longevity As Induced By Bean Leaf Beetle, Cerotoma Trifurcata And Soybean Looper, Pseudoplusia Includens Herbivory On Soybean, P. Srinivas, Stephen D. Danielson, C. Michael Smith, John E. Foster

Cross-resistance, and longevity of resistance, induced by the bean leaf beetle, Cerotoma trifurcata, was studied IN the soybean PI 227687 that exhibited induced response in earlier studies. Bean leaf beetle adults and soybean looper, Pseudoplusia includens, larvae were used to induce resistance and to determine beetle feeding preference. Beetles were collected from soybean fields 2 to 5 days prior to the feeding preference test. The level of cross-resistance induced by soybean looper herbivory to subsequent bean leaf beetle feeding was higher when compared to cross-resistance induced by bean leaf beetle herbivory against subsequent feeding by soybean looper. Further, herbivory by …
