abstract={This study assessed the pesticidal activities of <i>Phytolacca dodecandra</i> extracts in controlling <i>S</i><i>itophilus </i><i>zeamais</i> and <i>T</i><i>ribolium castaneum</i> pests in stored maize grains. The study was conducted at ambient conditions (25¨C30¡ãC and 65¨C70% relative humidity) and designed in a completely randomised design with 8 treatments in triplicate. Contact toxicity, percent mortality, feeding deterrence and grains weight loss were assessed using developed procedures for 21 days and first filial generation progeny was assessed for 42 days of post-pest introduction. Both ethanolic root and leaf extracts of <i>P. dodecandra</i> demonstrated significant bioactivities against both <i>S. zeamais</i> and <i>T. castaneum</i>, with the leaf extract being more active than the root extracts. <i>P. dodecandra</i> leaf extracts killed 98% of <i>S. zeamais</i> and 99% of <i>T. castaneum</i> at concentration of 150 mg/mL on day 3. Similarly, <i>P. dodecandra</i> leaf extracts reduced grain damage to 0% and had moderate repellence of 57% and 66% to <i>S. zeamais</i> and <i>T. castaneum</i>, respectively. Hence, after biosafety studies this plant-based products can be included in the Integrated Pest Management strategies and can be recommended as an alternative remedy in treating maize storage pests in subsistence agriculture. Further isolation and structure elucidation of bioactive ingredients in the plant species are recommended and are underway.},
