Red clover (Trifolium pratense) seed yields in Oregon are significantly reduced by the Clover Root Borer (CRB), Hylastinus obscurus. Since the CRB develops in clover roots and only emerges above ground briefly to mate and disperse, insecticides are ineffective for its control. In contrast, biological control may have potential as the entomopathogenic fungus Beauveria bassiana was observed infecting CRB in the field. The objective of this study was to determine whether B. bassiana would transfer horizontally between conspecifics. The results indicate that 67% of beetles died when exposed to the higher dose tested under laboratory conditions. Further research is needed to determine the efficacy of B. bassiana under field conditions.
