Optimizing European Corn Borer (Lepidoptera: Pyralidae) Infestation of Maize Ears for Kernel Damage Evaluations
Four maize, Zea mays, L., genotypes, 'Jubilee,' B52, W182E, and 'Apache,' were infested at the ear tip with 0, 2, 4, 8, 16, or 32 egg masses of Ostrinia nubilalis (Hübner) and evaluated for kernel damage. Averaged across genotypes, kernel damage first increased and then approached a plateau as infestation level increased. Ability to differentiate among genotypes, measured as F in separate analyses of variance at each infestation level, was estimated to be maximized with ca. 9 egg masses per ear tip. A significant F (P ≤ 1%) would have been achieved with three replications and four egg masses per ear tip.
