Interpretive Summary: The objective of this study was to find entomopathogenic fungi (EPF) from the rhizosphere of Nebraska cornfields and test them against a major pest of continuous corn, the western corn rootworm (WCR), Diabrotica virgifera virgifera (LeConte). Twenty-four field-collected EPF strains, plus a commercial comparison (BotaniGard 22WP) and negative control were tested against third instar D. v. virgifera larvae in soil mortality assays.
