Granular base formulation for the incorporation of biologically-effecting active ingredients for the control of simbiotic fungus grown by leaf cutting ants, Atta spp. Leaf cutting ants (Atta spp.) can destroy complete plantations of economically important crops in Tropical and Subtropical America, by cutting plant tissues and transporting them to underground nests where they grow a fungus of the Basediomycota Phylum which is their main food resource. At present, no effective management strategy for this pest is available. Most of the products in the market are poorly effective, are residual in the environment and have a high price. The present investigation evaluated different ingredients used in granular preparation that have been reported as carried away by ants, with potential of being incorporated as active ingredients against the leaf cutting ants’ symbiotic fungus. Granules with different combinations and concentrations of inert ingredients were prepared, using citrus pulp, alcoholic extracts of orange peel and seeds as attractants. In order to verify the compatibility of RESUMEN Las hormigas forrajeras (Atta spp.) pueden destruir plantaciones completas de hortalizas y de otras plantas de importancia economica en America Tropical y Subtropical. Cortan el tejido de las plantas y lo transportan a nidos subterraneos, donde cultivan un hongo del Phylum basidiomycota, que es su alimento principal. En la actualidad, no se cuenta con una estrategia efectiva de manejo de esta plaga. La mayoria de productos disponibles comercialmente son muy poco efectivos, dejan residuos en el ambiente y tienen un precio alto para los pequenos agricultores. La presente investigacion se propuso evaluar diferentes ingredientes en la preparacion de granulados que presenten alto nivel de acarreo y potencial para la incorporacion de ingredientes activos con efecto biologico contra el hongo simbiotico que cultivan las hormigas forrajeras. Se prepararon granulos con diferentes combinaciones y concentraciones de excipientes o coadyuvantes. Ademas se evaluo citropulpa, extracto alcoholico de cascaras de naranja y aceite de semillas de naranja, como atrayentes.
