Laboratory experiments were carried out to investigate the efficacy of seed extracts of pithraj, Aphanamixis polystachya (Wall & Parker), a locally grown plant in Bangladesh, against the red flour beetle, Tribolium castaneum (Herbst.). Results of three different bioassays showed that crude extracts of pithraj seeds have strong repellent effects and moderate feeding deterrent and insecticidal (direct-contact) effects on adult Tribolium castaneum.
