Abstract:A temperature-dependent model designed to predict emergence of first-generation adult southwestern corn borer, Diatraea grandiosella Dyar, was developed and validated. Thermal unit requirements were determined for larval, prepupal, and pupal development for nondiapausing southwestern corn borer at three constant temperatures. Data input to the model were average daily mean maximum and minimum temperatures and the age class (instar) distribution of field-collected larvae. Model predictions agreed closely with observed adult emergence during 4 yr of field validation. Fifty to 69% of the predicted dates were within Â±2 d of the observed emergence date for 5, 25, and 50% adult emergence. Application of the developmental model to an integrated pest management program for corn is discussed.
