supervised by Dr John Brady, an expert in the circadian control of behaviour in tsetse fly, where she extended her techniques in video-recording of flight behaviour in laboratory to field studies in Zimbabwe. She demonstrated that tsetse do not ‘see’ zebras, and therefore, rarely feed on them, and that tsetse use a novel mechanism for using host odours to locate favoured hosts. Over the course of four field season she also witnessed the development of the famous tsetse traps and targets developed by Vale, Hargrove, Torr, Hall and others, which has become the iconic case-study that shows basic principles of sensory control of behaviour are key to the design of successful surveillance and control devices
