Marjorie Ann Hoy (19 May 1941[1] – 19 June 2020) was an American entomologist and geneticist known for her work using integrated pest management (IPM) and biological control in agriculture.
She was Professor and Eminent Scholar at the University of Florida, Fellow of the Royal Entomological Society of London, the American Association for the Advancement of Science, and Entomological Society of America.
[3] Hoy was known as a pioneer in using genetic engineering to reduce the impact of agricultural pests, including developing pesticide resistant predators to control populations of destructive pests in areas where pesticides are applied.
[2][4] Her books include the textbook Insect Molecular Genetics, the third edition of which was published in 2013.
She was Research Entomologist at the Connecticut Agricultural Experiment Station (1973–1974) and U.S. Forest Service Northeast Forest Experiment Station (1974–1976) before joining the faculty at University of California, Berkeley, where she worked from 1976 to 1992.
