Se valido la adicion de polvos vegetales y minerales al maiz almacenado como proteccion contra el dano de insectos, tomando como criterio el numero de insectos vivos y muertos y el peso del grano. Se encontro que el polvo del vegetal Ricinus communis fue el mas eficiente para proteger al grano contra Sitophilus zeamais Motsch y Rhyzoperta dominica Fabr. El mineral teckies ligero fue el mas eficiente contra Prostephanus truncatus (Horn) R. dominica entre siete polvos vegetales y cinco minerales, evaluados en tres localidades de Mexico. Addition of vegetal and mineral powders to stored corn as protection against insect injury was validated. Criteria were the number of alive and dead insects and corn weight. Ricinus communis was the most efficient to protect the kernels from Sitophilus zeamais Motsch and Rhyzoperta dominica Fabr. attack, and the mineral powder "teckies ligero" was the most efficient to protect the kernels for Prostephanus truncatus and R. dominica damage among seven vegetal and five mineral powders evaluated in three localities of Mexico.
