Marion Sidney Mayer, PhD, Research Entomologist at the United States Department of Agriculture, has been recognized by Marquis Who’s Who Top Scientists for dedication, achievements, and leadership in entomology.

Long fascinated by entomology, Dr. Mayer earned a Bachelor of Science from Louisiana State University in 1957. Following this accomplishment, he joined the U.S. Army Reserves in 1958, and remained active as a reservist until 1964. During this time, he matriculated at Texas A&M University, from which he earned a Master of Science in 1961 and a Doctor of Philosophy in 1963. Dr. Mayer’s doctoral dissertation served as an assessment on the efficacy of using radioactive isotopes to locate overwintered boll weevils, which yielded evidence that the weevils would begin to die seven days following their initial exposure.

After Dr. Mayer’s initial employment in 1973 by the U.S. Department of Agriculture in Gainesville, he began studying the effects of human airborne odors on mosquito olfactory mediated behavior, and is proud that his particular research group performed all of its testing correctly. Additionally, he was the first to show that mosquito eggs hatch rates exponentially decline relative to the level of environmental water immersion. Dr. Mayer also demonstrated the existence of a hydrocarbon-based compound that is highly attractive to houseflies, which is now used in many commercial traps.

Throughout the course of his long tenure in research, Dr. Mayer served as an entomologist for the U.S. Department of Agriculture from 1963 until his retirement in 2000. During the span of his career, he notably authored a book chapter on behalf of one of his colleagues, “Insect Pheromones and Sex Attractants” in 1990. As a testament to his success, Dr. Mayer received an Albert Nelson Marquis Lifetime Achievement Award in 2020. He is also listed in the 24th and 25th editions of Who’s Who in the South and Southwest.
