Professional Summary:

Patricia V. Pietrantonio, Ph.D., is a professor in the Texas A&M University Department of Entomology. Her research and teaching interests are in Insect Toxicology and Insect Physiology, utilizing organismal, biochemical, molecular, and cellular approaches. Her research scope includes discovering novel targets for arthropod control, with emphasis on G protein-coupled receptors. Target-based high-throughput screening of small molecule libraries yields novel stable chemicals for physiological research. The focus is on invasive disease vectors (mosquitoes and ticks), and fire ants. Other areas of emphasis are detection and monitoring of insecticide resistance in mosquito vectors of arboviruses and in lepidopteran pests of cotton. Over the past five years, she has obtained more than $2.4 million in funding to her research program and about $7 million dollars for her career. Pietrantonio’s publications have 3,892 citations with 1,249 since 2017. She is the President of the Acarological Society of America 2022 and serves in the Editorial Boards of the journals Insect Biochemistry and Molecular Biology, and Archives of Insect Biochemistry and Physiology. Until 2021 she was Associate Editor of Pest Management Science.
