The western bean cutworm is a major corn pest in Nebraska, posing a severe threat to developing ears, harming overall plant health and production. The application of insecticides and the use of managed hybrids are important mitigation tools, but their effectiveness on the cutworm is declining with every season. Broad-spectrum insecticides may reduce populations of beneficial insects, disrupt natural pest controls and create ecological imbalance. This study evaluates bio-based mitigation strategies to manage cutworm populations in Nebraska corn fields while minimizing impacts on other insects in the environment. The goal is to provide growers with additional options to diversify pest control, reduce reliance on a single mode of action while targeting a longstanding corn pest.
