Professional Responsibilities and Activities:

The Agroecosystems Entomology Lab, located at the West Central Research & Extension Center in North Platte, pursues research questions addressing the ecology and management of agricultural pests with an emphasis on practical applications for integrated pest management in field crops. Current research projects may address a variety of themes, such as food web dynamics, insect behavior, compatibility of pest control strategies (including biological control by natural enemies), and resistance management. Our research supports extension programming to develop proactive educational programs in IPM and IRM of arthropod pests of field crops grown in west central Nebraska.
