Sumario:Essential oils are biologically and environmentally safe pesticidal compounds yielded from aromatic plants. Spices are important sources of essential oils, and they are widely used in the medicine, food, and various other industries. Among the different spices, Allspice (<i>Pimenta dioica</i>) is underexplored in terms of its biological efficacy and a limited number of studies are available on the chemical composition of Allspice essential oil (AEO); thus, the present study evaluated the larvicidal property, the repellency, and the fumigant toxicity against common pests of stored products of AEO. AEO was found to inhibit the survival of larvae of such vectors as <i>Aedis, Culex</i>, and <i>Armigeres</i> species. Further, AEO was found to exert repellant effects against the pests of such stored products as <i>Sitophilus, Callosobruchus,</i> and <i>Tribolium</i>. Similarly, the fumigant toxicity was found to be high for AEO against these species. The contact toxicity of AEO was high against <i>Sitophilus</i> and <i>Callosobruchus</i>. Apart from that, the essential oil was found to be safe against a non-target organism (guppy fishes) and was found to be non-genotoxic in an <i>Allium cepa</i> model. Overall, the results of the present study indicate that the essential oil from Allspice could be used as an environmentally safe larvicidal and biopesticidal compound.
