Join Dr. Smitley on an investigative walk through mid-Michigan landscapes. Keep your eyes peeled for common pests from the 2017 season - and learn management strategies for when they reappear in the spring!
Michigan State University
Dr. Smitley works closely with the turfgrass, nursery and floriculture industries on identifying and solving insect pest problems, including best management practices for growers and landscapers. Basic and applied research is followed with extension recommendations for growers. In 1991, Dr. Smitley worked with Dr. Bauer to introduce Entomophaga maimaiga, a natural fungal pathogen of gypsy moth, into Michigan. E. maimaiga is now widespread throughout the state and is helping to suppress gypsy moth. In the last 10 years, research on emerald borer led to the development of new management strategies, including trunk injection of emamectin benzoate (TREEäge) to protect individual trees. Dr. Smitley also introduced Ovavesicula popilliae, a natural pathogen of Japanese beetle, into Michigan to help suppress populations of Japanese beetle. Research continues on the long-term impact of O. popilliae on Japanese beetle. At this time the Smitley lab is working on the development of new strategies for pest management in turfgrass, nurseries and greenhouses, and on evaluating the cost/benefit of neonicotinoid insecticides, including the potential impact on pollinators in the yard and garden. Several publications are now available on how to encourage and protect pollinators in the yard and garden.
