Abstract: The phytochemical composition of Tunisian Papaver rhoeas L. petals and capsule aqueous extracts and their antioxidant and insecticidal potential were investigated. Petals aqueous extracts showed the highest amounts of polyphenols (62.43 mg GAE/g DW) and flavonoids (21.08 mg RE/g DW). Aqueous extracts were found to possess antioxidant activities, as determined by scavenging effect. Petals aqueous extracts exhibited the strongest DPPH radical scavenging activity (IC50 = 28.06 mg/ml). Tribolium casteneum is a major stored grains pest causing huge loss by secreting toxic quinones’ which make the grains unfit for human consumption. Therefore, finding an eco-friendly alternative for the management of the pest is of great importance. In this study, the insecticidal activity of petals and capsule aqueous extracts is evaluated. Bioassays showed that capsule extracts exhibited insecticidal capacity (LC50=1.52, LC90=1.99). Consequently, P. rhoeas extracts species could be exploited as a natural source of bioactive compounds in food, pharmaceutical industries and pest control.
