Resumo: The weevil Sitophilus zeamais (Coleoptera: Curculionidae) is one of the main pests of stored corn. The use of synthetic insecticides is the main strategy for its management, which can cause unwanted effects such as the selection of resistant insects and residues. In this case, the search for less impactful products is desirable. This work evaluated the lethal and sublethal action of bioinsecticides formulated from Beauveria bassiana (Boveril®), Metarhizium anisopliae (Metarril®) and Isaria fumosorosea (Octane®) over S. zeamais. The lethal effect evaluations revealed that after 240 hours of exposure by direct contact at a concentration of 1.0 × 107 conidia.mL-1, Boveril® caused a mortality of 77%, being higher than that verified for Metarril® (10.8 %) and Octane® (9.4%). Residual contact with 1.0 × 107 conidia.mL-1 caused a maximum mortality of 5% for the evaluated bioinsecticides. The evaluation of sublethal effects didn’t indicate significant differences in the instantaneous growth rates (ri) of S. zeamais populations held for 90 days in substrate sprayed with 1.0 × 107 conidia.mL-1 of each of the bioinsecticides and a control where sterilized distilled water was used. In the conventional choice attractiveness test, the Boveril® treatment presented 11.2% of insects, indicating possible repellency, with no differences between the other bioinsecticides and the control formed by sterilized distilled water. Boveril® was the most promising among the tested bioinsecticides, showing a probable repellency and causing a significant mortality of S. zeamais via direct contact.

El uso de insecticidas sintéticos es la principal estrategia para su manejo, lo que puede ocasionar efectos no deseados como la selección de insectos resistentes y residuos. En este escenario, es deseable la búsqueda de productos de menor impacto. Este trabajo evaluó la acción letal y subletal de bioinsecticidas formulados a partir de Beauveria bassiana (Boveril®), Metarhizium anisopliae (Metarril®) e Isaria fumosorosea (Octane®) sobre S. zeamais. Las evaluaciones del efecto letal revelaron que después de 240 horas de exposición por contacto directo a una concentración de 1,0 × 107 conidios.mL-1, Boveril® provocó una mortalidad del 77 %, siendo superior a la verificada para Metarril® (10,8 %) y Octane® (9,4%). El contacto residual con 1,0 × 107 conidios.mL-1 provocó una mortalidad máxima del 5% para los bioinsecticidas evaluados. La evaluación de efectos subletales no indicó diferencias significativas en las tasas de crecimiento instantáneo (ri) de las poblaciones de S. zeamais mantenidas por 90 días en sustrato rociado con 1.0 × 107 conidios.mL-1 de cada uno de los bioinsecticidas y un control donde se utilizó agua destilada esterilizada. En la prueba de Prueba de elección de atractivo, el tratamiento Boveril® presentó 11,2% de insectos, indicando posible repelencia, sin diferencias entre los demás bioinsecticidas y el testigo formado por agua destilada esterilizada. Boveril® fue el más prometedor entre los bioinsecticidas probados, mostrando una probable repelencia y provocando una mortalidad significativa de S. zeamais por contacto directo.O gorgulho Sitophilus zeamais (Coleoptera: Curculionidae) é uma das principais pragas do milho armazenado.
