Interpretive Summary:

Technical Abstract: Plant resistance factors can affect the viability of insect fungal pathogens. Plant varieties may have different levels of plant pathogen resistance, which could affect pest control with insect pathogens. Leaves from twelve maize inbreds with varying resistance to Fusarium and/or Aspergillus pathogens were evaluated for their influence on mortality when different commercial strains of Beauveria bassiana were applied to maize tissue and fed to European corn borers (Ostrinia nubilalis) and fall armyworms (Spodoptera frugiperda). Significant differences in mortality were noted for first instars on day two of assays of both insect species fed on B. bassiana treated leaves from different inbreds. In some cases there were large differences in efficacy for the same strain and inbred between the different insect species.
