Egg incubation is done by mixing 0.1 gram of Corcyra eggs in 40 grams corn bran and stored at room temperature. Results showed that there was no emergence of the feed competitors, Tribolium castaneum, in feed media infested with Corcyra eggs incubated for 15 and 20 days. Minimal tribolium population were observed in 10 days incubation. Feed media infested with newly laid and 5 days incubated corcyra eggs had high infestation of tribolium. High egg production were observed from the moths hatched from 10, 15, and 5 days incubation, respectively. Moths from newly hatched and 20 days incubation had low egg production. This indicates that the feed competitor T. castaneum can be controlled and high corcyra egg production can be obtained in eggs incubated for 10-15 days
