Enhanced rates of lethality to fall armyworms (Spodoptera frugiperda) after association of Beauveria bassania strain ant 03 with sweet corn leaves.
Beauveria bassiana (Bals.-Criv.) Vuill. is a valuable biological control agent for insects. B. bassiana efficacy can be influenced by plant interactions, including secondary metabolites, but the range of interactions with maize are not well understood. B. bassiana-treated sweet corn leaf tissue that had been fed on by fall armyworms, Spodoptera frugiperda (J.E. Smith), caused a significantly higher rate of mortality compared to leaf tissue provided to fall armyworms immediately after fungal treatment. These results suggest the ability of B. bassiana to interact with plant tissue should also be considered in selecting strains for commercial development.
