Biologist Physiology Zoology Entomology Insecticides Education: St Catherine's College, University of Cambridge, MA in natural sciences (1959); University of Cambridge, PhD (1962) Career: Postodoctoral Researcher, Dalhousie University, Canada (1962-1964); Fellow of Gonville and Caius College, University of Cambridge (1964-2007), Life Fellow (2007-2020); ARC Unit of Invertebrate Chemistry & Physiology, Department of Zoology, University of Cambridge (1968-1990); Honorary Reader of Comparative Physiology, Department of Zoology, University of Cambridge (1990-2003); Honorary Professor of Integrative Physiology, University of Cambridge (2003-2008); Emeritus Honorary Professor, Department of Zoology, University of Cambridge (2008-2020) Simon Maddrell made elegant contributions to the study of the excretory system of insects, devising improved techniques for measuring secretory activity of Malpighian tubules in vitro. He discovered the existence of a diuretic hormone in Rhodnius, derived from neurosecretory cells in the thoracic ganglia and liberated commonly by exocytosis, from axon terminations along the abdominal nerves. He found that many insecticides induce release of diuretic hormone and this may be one reason for their effectiveness. Neurohormones were also shown to control the plasticity of the cuticle. Simon’s methods have been widely employed in the search for hormones affecting insect water balance, as well as many epithelial transport processes.
