Abstract
Based on rate of larval development, the confused flour beetle, Tribolium confusum (Duval), consistently differentiated among selected cereal cultivars provided as food. Although variations occurred in ranking order from test to test, some cultivars always permitted faster larval development than others. There was good correlation between results from tests with the beetles and from those with chicks fed the same rations. Addition of minerals and micronutrients to the cereals changed the nutritional value for the beetles but the extent of change was not uniform among the cultivars.
