Bioactive silo bag for controlling stored pest: Sitophilus zeamais (Coleoptera: Curculionidae)
Corn weevil, Sitophilus zeamais Motschulsky, is a primary pest of stored grain causing significant quantitative and qualitative loss worldwide; its control mainly depends on synthetic insecticides such as organophosphates and pyrethroids. Several organic compounds derived from plant such as ketones...

| Sumario: | Corn weevil, Sitophilus zeamais Motschulsky, is a primary pest of stored grain causing significant quantitative and qualitative loss worldwide; its control mainly depends on synthetic insecticides such as organophosphates and pyrethroids. Several organic compounds derived from plant such as ketones represent “green” alternatives to conventional pesticides. The aim of this study was to develop a bioactive silo bag with natural formulation consisting of plant-based ketones (binary mixture of thymoquinone and pulegone 1:1 mass ratio) in its inner layer (LDPE) to compare the efficiency of the process and relationship with the physicochemical properties of the molecules. Thus, we evaluated their optical, chemical, mechanical and biological properties. No differences in the morphology between the active and control silo bags were found. The repellent and insecticidal activities of the bioactive silo bag were tested against S. zeamais, primary pest of storage crops, showing a repellent index (RI) around 70% and 100% mortality, respectively. Therefore, a formulation with organic compounds (pulegone and thymoquinone) incorporated in the hermetic structure of the storage system could be used as an eco-friendly tool for sustainable pest management. |
