As the SDSU Extension Field Crop Entomologist I serve South Dakota stakeholders by addressing insect pest issues in field crops. I conduct applied research that focuses on corn, soybean, wheat and sunflower. I also assist the other extension entomologists to address questions pertaining to insect questions for the home and garden, urban insect pests and general entomology questions.
