James H. Tumlinson

James Homer Tumlinson III, born 1938 in Mississippi and died February 9, 2022, in Gainesville, Florida, was an American entomologist and chemical ecologist who spent more than thirty years as a research chemist and research leader with the United States Department of Agriculture's Agricultural Research Service in Gainesville before serving as a professor of entomology at Pennsylvania State University. He was known for identifying insect pheromones and other semiochemicals, including the boll weevil pheromone that became a key component of the boll weevil eradication program, and his research uncovered mechanisms governing plant-insect and plant-plant chemical interactions that advanced environmentally safe pest management. He was elected to the National Academy of Sciences and received the Wolf Prize in Agriculture in 2008 for these discoveries.
