Larval growth rates, adult emergence, egg hatch, and F1 progeny production of Tribolium confusunJacquelin duVal on wheat flour diets containing 0.05, 0.5, 2.0, and 5.0% (wt/wt) of sorbic acid, calcium propionate, methylparaben, BHT, BHA, or propyl gallate were determined.

Sorbie acid at 0.5, 2.0, and 5.0% in the diet suppressed T. confusum through direct ovicidal effects on the eggs. BHA and BHT at dosage levels of, and 5.0% in the diets inhibited larval growth and were ovicidal at the 2 and 5% levels. No cumulative or synergistic effects of several combinations of BHA, BHT, and sorbic acid were observed.
