Abstract

The effectiveness of microbial controls for pest ants can be reduced by ant behaviors. Introductions of pathogens, including nematodes, into ant nests result in behavioral responses by ants that affect infection rates to ants exposed to inocula, affect the dissemination of inocula among nestmates, and affect the dispersal of inocula outside the nest. These behaviors include grooming, secretion of antibiotics, nest hygiene, avoidance, and dispersal. Ant behaviors must be considered in developing microbial control agents. Approaches to overcoming the behavioral responses of the red imported fire ant to the entomopathogen Beauveria bassiana (Balsamo) Vuillemin are discussed. /// La eficiencia del control microbiano contra hormigas plaga puede ser reduzida devido al comportamiento de las hormigas. La introducción de patógenos, incluyendo neámtodos, en el nido de las hormigas lleva a cambios comportamentales que afectan la porcentaje de infección de las hormigas expuestas al inóculo, la dispersión del inóculo entre las hormigas de un mismo nido, y la dispersión del inóculo fuera del nido. Estos comportamientos incluyen limpieza del cuerpo de las hormigas, secreción de antibióticos, higiene del nido, el evitar al patógeno, y dispersión de las hormigas. El comportamiento de las hormigas deve ser considerado durante el desarrollo de agentes microbianos para control biológico. Propuestas para superar las respuestas comportamentales de la "hormiga brava" al entomopatógeno Beauveria bassiana (Balsamo) Vuillemin.
