Temperature-dependent model for postdiapause development and spring emergence of the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Pyralidae), in North Carolina
Environmental Entomology 11 (6), 1307-1311
Abstract: Parameters were estimated for a temperature-dependent model of postdiapause development and spring emergence of the overwintering generation of European corn borer (ECB) in North Carolina. Controlled-temperature studies examined ECB postdiapause development at several constant temperatures: 13.7, 15, 17.2, 18, 19.2, 22, 25, 30, 32, and 35 ± 1°C. From these data, development rate vs. temperature curves were constructed and incorporated into a model predicting ECB spring emergence for 10, 50, and 90% of the overwintered generation. The model was validated by using temperature data and blacklight trap records from four counties in eastern North Carolina. The model provided good prediction at all percentiles of emergence, but there was a tendency toward early predictions at the 90% level.
