Stanley Dwight Beck (October 17, 1919 – July 8, 1997) was an American entomologist who specialized in insect physiology and host plant resistance. He became a university researcher after a stint in the navy during World War II. Paralyzed by polio and reliant on a wheelchair from 1952 he continued his research. He worked on insect photoperiodism and wrote two major books Animal Photoperiodism (1963) and Insect Photoperiodism (1968). Among his contributions was the successful development of artificial diets for lepidopteran larvae which enabled controlled laboratory experimentation and research on several pest species. After his retirement he published Two in the Game, a novel.
