Abstract
A method is described of screening corn, Zea mays L., for resistance to the European corn borer, Ostrinia nubilalis (Hübner), in the laboratory by adding lyophilized plant material to the insect diet. Measurement of larva length at 10 days is sufficient to show differences in growth response to feeding on the resistant or susceptible plant material.
