The objective of this study was to evaluate different doses of butylated hydroxytoleuene (BHT) against the confused flour beetle, Tribolium confusum Jacquelin du Val (Coleptera: Tenebrionidae). The effects on feeding behavior, growth, food consumption and total protein content of insects treated with different doses (1.48, 3.18, 6.36 and 9.54 mg g−1) of BHT were evaluated. Antifeedant activity was observed only at 1.48 mg g−1 in the choice assay, with a feeding deterrence index (FDI) of 0.41; this concentration also deterred feeding by 41.6%. All treatments showed feeding suppression index (FSI) and feeding inhibition index (FII) as
