Resumo: | This study aimed to evaluate the pathogenicity of the entomopathogenic fungus Metarhizium anisopliae on leaf-cutting ants Atta sexdens rubropilosa, under laboratory conditions. It was inoculated suspensions containing different concentrations of conidia on specimens of soldiers and workers, kept under controlled conditions. The mortality was verified daily until 15 days after inoculation. The experimental delineation was entirely random. Sporulation data were submitted to variance analysis and the average of the treatments were compared to each other by the Scott-Knott test. Probit analysis was performed to obtain the values of LT50 (in days). All isolates were pathogenic to A. sexdens rubropilosa, being more virulent for workers than for soldiers. Isolates IBCB 348, IBCB 410 and IBCB 425 were the most efficient in the mortality of the ants. Isolates IBCB 425 and UFGD 03 caused high percentages of confirmed mortality. The results showed that the tested isolates have the potential for using them as control agents of A. sexdens rubropilosa. |

Se inocularon suspensiones que contenían diferentes concentraciones de conidios en especímenes de soldados y trabajadores, mantenidos en condiciones controladas. La mortalidad se controló diariamente hasta 15 días después de la inoculación. El diseño experimental utilizado fue completamente al azar. Los datos de esporulación se sometieron a análisis de varianza y las medias de los tratamientos se compararon mediante la prueba de Scott-Knott. Se realizó análisis probit para obtener valores de TL50 (en días). Todos los aislados fueron patógenos para A. sexdens rubropilosa, siendo más virulentos para los trabajadores que para los soldados. Los aislados IBCB 348, IBCB 410 e IBCB 425 fueron los más eficientes en la mortalidad de hormigas, IBCB 425 y UFGD 03 provocaron altos porcentajes de mortalidad confirmada. Por lo tanto, los aislamientos probados tienen potencial para su uso como agentes de control de A. sexdens rubropilosa.O objetivo deste trabalho foi avaliar a patogenicidade do fungo entomopatogênico Metarhizium anisopliae sobre formigas cortadeiras Atta sexdens rubropilosa, em condições de laboratório. Foi realizada a inoculação de suspensões contendo diferentes concentrações de conídios em exemplares de soldados e operárias, mantidos sob condições controladas. A mortalidade foi verificada diariamente até 15 dias após a inoculação. O delineamento experimental utilizado foi o inteiramente casualizado. Os dados de esporulação foram submetidos à análise de variância e as médias de tratamentos comparadas pelo teste de Scott-Knott. Foi realizada análise de Probit para obtenção dos valores de TL50 (em dias). Todos os isolados foram patogênicos a A. sexdens rubropilosa, sendo mais virulentos para operárias do que para soldados. Os isolados IBCB 348, IBCB 410 e IBCB 425 foram os mais eficientes na mortalidade das formigas, IBCB 425 e UFGD 03 causaram altas porcentagens de mortalidade confirmada.
