Popis:	The effect of egg age and storage temperature and duration on the percentage of hatch and time to 50% hatch for eggs of Diabrotica undecimpunctata howardi Barber, southern corn rootworm, was determined by exposing 1-, 3-, and 5-d-old eggs at 6 temperatures from 0 to 15°C for durations of 1-6 wk. Egg age, storage temperature, storage duration, and their interactions had a significant influence on percentage of egg hatch and time to 50% hatch. Regression models were developed to allow prediction of percentage of hatch and time to 50% hatch. Eighteen treatment combinations maintained egg viability >94%. Percentage of hatch and time to 50% hatch were optimized with 1-d-old eggs incubated at 15°C for 3 wk.
