The first generation larvae of oriental corn borer were fed dent corns at the vegetative or the reproductive stage, and the second generation larvae were fed corns at the ripening stage in Morioka, Tohoku district. Upon the examination of the specimens from a dent corn field, it was found that the second generation larvae showed higher survival and developed into slightly lighter pupae than those of the first generation. In green house experiments with potted dent corns, the larvae fed upon the late reproductive stage of corn showed the highest survival and the heaviest weight of all. Larvae fed upon the vegetative stage of corn showed low survival and low weight. At the late ripening stage of corn, the larvae showed high survival, but low weight. From the results obtained, it was concluded that the differences in survival and weight of larvae between two generations in the field could be ascribed to the difference in growth stages of corn fed to the larvae.
