Douglas Frew Waterhouse AO CMG (1916-2000), entomologist, identified the active ingredients for the insect repellent later marketed as Aerogard. As head of the Entomology division of CSIRO from 1960 to 1981, he championed the use of the dung beetle for biological control of bush flies. He was the driving force behind the Australian National Insect Collection, the Stored Grain Research Laboratory and the use of nematodes and synthetic sex pheromones for controlling insect pests. Over the course of his career he oversaw a number of valuable pest management projects in Papua New Guinea, Asia and the Pacific. He was a Fellow of the Royal Society and the Australian Academy of Science and the recipient of numerous awards and medals.
