Abstract
Life table parameters were estimated for Ostrinia nubilalis (Hubn.) fed on an artificial diet at serial constant temperatures viz: 18, 22, 26 and 30°C. The optimum temperature was estimated as 26°C characteristic, with the highest net reproductive rate (236) expected females/ female. Mean generation duration was 76.6 days at 18°C, while it was 28.7 days at 30°C. The average thresholds of development was 11.75 °C, while the degree- days required for completion of one 0. nubilalis generation was 475.47 DDU.
