Angela E. Douglas

Angela Elizabeth Douglas (born 1956) is a British entomologist who researches insect nutrition, and is known for her research on symbiotic relationships between insects and microorganisms. She has been the Daljit S. and Elaine Sarkaria Professor of Insect Physiology and Toxicology at Cornell University, Ithaca, New York, since 2008, and previously held a chair at the University of York (2003–8). She held postdoctoral positions at the University of Oxford (1981–85) and the University of East Anglia (1985–86). Her subsequent work has mainly focused on symbioses between insects and bacteria. A major focus since the mid-1980s has been the question of how insects that feed exclusively on plant phloem, such as aphids, survive even though their food source lacks essential nutrients. She was the first to prove that the aphids receive essential amino acids from symbiotic bacteria.

Douglas is an elected fellow of the Royal Entomological Society and the Entomological Society of America (2011), and won the latter's Recognition Award in Insect Physiology, Biochemistry, and Toxicology in 2015. She also won Kiel University's inaugural Karl August Möbius Fellowship in 2017. She has written several books, including The Symbiotic Habit (2010),
