AbstractBased 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.

AbstractThe fat soluble components of raw wheat germ were extracted with diethyl ether, and the extracts assayed for aggregant or arrestant activity with adults of the confused flour beetle, Tribolium confusum. Some extracts elicited a strong response, others had little effect, and still others were repellent. The concentration of peroxide in the ether was shown to be inversely correlated with the aggregating response evoked by the extract. In the preparation of extracts of biological material, therefore, solvents other than ether should be used unless the peroxide component is completely eliminated immediately before use.
