The treatments were: unharvested control, harvested-only, mowed, disked, disked-bedded, and mowed–disked. All treatments reduced O. nubilalis survival compared with the unharvested control. O. nubilalis survival was least during both years in plots that were both mowed and disked. O. nubilalis emergence was significantly earlier in the mowed–disked treatment compared with the harvested-only treatment. The duration of emergence per treatment was longest in the unharvested control and harvestedonly treatments compared with other treatments.}, number={4}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={UMEOZOR, OC and VANDUYN, JW and BRADLEY, JR and KENNEDY, GG}, year={1985}, pages={937–939} }

There was a significant relationship between grain weight and cavities per plant in 10 of 12 fields surveyed. In controlled experiments in 1982 and 1983, a more significant relationship was observed between grain weight and cavities per plant. Reduction in maize yield by O. nubilalis ranged from 102.72 to 465.79 kg/ha per cavity. Yield reduction was affected by infestation date, infestation level, and year (rainfall). In these experiments, variation in maize yield accounted for by cavities ranged from 4.1 to 54.3%. Damage potential of O. nubilalis to maize was not significantly different at 49,000 and 69,000 plants per ha.}, number={6}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={UMEOZOR, OC and VANDUYN, JW and KENNEDY, GG and BRADLEY, JR}, year={1985}, pages={1488–1494} }
