Five commercial corn hybrids were evaluated for ear corn yield and damage by Sitophilus oryzae (L.). Hybrid plots were artificially infested by 3 methods: doghouses, birdhouses, and tepees. Paired rows within each plot were used for slit- and unslit-husk treatments. Differences in yield and damage among infestation method means were not significant at the 5% level. When husks were slit, hybrid differences indicated that factors other than husk tightness contributed to insect resistance. On the basis of cost, effort, and analyses, considering standard errors, means, and correlations, the birdhouse method of infesting and rating by degree damage per infested car was chosen as the best combination for producing artificial infestations and evaluating damage.
