Larry Gut, MSU professor, remembered as a leading scientist, ag supporter
Professor Lawrence “Larry” Jerome Gut died Sept. 6, 2021, in Wenatchee, Washington, where he recently moved with his wife Kathleen Gut to retire near family and friends.
According to a Sept. 20 announcement by Michigan State University (MSU), Gut joined MSU’s Department of Entomology in 1997. He developed a deep understanding of the biology of insect pests that threaten Michigan’s tree fruit crops and applied that knowledge to reduce their economic impact. His innovative studies and research into insect behavior and ecology made him an internationally recognized expert on tree fruit Integrated Pest Management. He traveled extensively to share his work with researchers and growers around the world.
Some of his most impactful studies focused on a key pest of global apple and pear production, the codling moth, leading to many of the basic and applied insights that allow economically and environmentally sustainable management of this pest using its sex pheromone. Recently, he focused his team’s attention on invasive pests of fruit crops, researching various new approaches to their control.
Gut’s commitment to agriculture extended to his Extension mission, translating research into printed and electronic guides to disseminate research-based recommendations to growers in Michigan, across the United States, and the world. Through numerous workshops, meetings at growers’ farms and presentations at regional, national and international events, he shared his team’s latest understanding of insect pest management. As an expert on managing moth pests, his advice was consistently sought by his research and extension colleagues and fruit growers. He also served as an expert witness in court cases on pest management failures.
Gut’s teaching and mentoring focused on training the next generation of applied entomologists. During his career he mentored seven postdocs, eight doctoral candidates and 10 masters students while also serving on many other thesis and dissertation committees. He regularly went above and beyond in supporting his mentees, including providing temporary housing for international students. Many of Gut’s trainees are now employed in university, government or industry positions where they continue to push the science of insect pest management forward.


To honor his legacy, an endowed scholarship in Gut’s memory has been established in the Department of Entomology at Michigan State University.
