Alexander Gaffke

Dr. Alexander Gaffke is a Research Entomologist at USDA-ARS-CMAVE since 2022, focusing on chemical ecology and biological control. His interdisciplinary work integrates analytical chemistry, insect behavior, and agronomy to enhance multitrophic interactions for pest management. He holds a Ph.D. and B.S. in Environmental Sciences from Montana State University. Dr. Gaffke has secured over $250,000 in grants and advises federal, state, and tribal agencies. His research emphasizes semiochemical applications for weed biocontrol, entomopathogenic nematode dynamics, and minimizing non-target impacts. He actively mentors graduate students and presents at national/international conferences.

Key research areas include optimizing biological control agents via semiochemical lures, investigating plant-insect-microorganism signals, and resolving ecological conflicts like tallow tree control and beekeeping safety. His lab’s work bridges chemical ecology with practical agronomic solutions, addressing invasive species management and sustainable crop production.

Dr. Gaffke’s grant-funded projects and advisory roles highlight his commitment to applied research, translating ecological insights into actionable strategies for environmental stewardship and agricultural resilience.
