Resumen:
orn weevil, Sitophilus zeamais Motschulsky, is a primary pest of stored grain causing significant quantitative and qualitativeloss worldwide; its control mainly depends on synthetic insecticides such as organophosphates and pyrethroids. Several organiccompounds derived from plant such as ketones represent “green” alternatives to conventional pesticides. e aim of this studywas to develop a bioactive silo bag with natural formulation consisting of plant-based ketones (binary mixture of thymoquinoneand pulegone 1:1 mass ratio) in its inner layer (LDPE) to compare the efficiency of the process and relationship with thephysicochemical properties of the molecules. us, we evaluated their optical, chemical, mechanical and biological properties. Nodifferences in the morphology between the active and control silo bags were found. e repellent and insecticidal activities of thebioactive silo bag were tested against S. zeamais, primary pest of storage crops, showing a repel
