Characterising colour vision in insect vectors of disease and agricultural pests
Harmful insects can be controlled by insecticidal traps, which often rely on olfactory cues to attract the target insects. However, exploiting insect colour preference to design more efficient traps has proved a successful, low environmental impact technique for one bloodsucking insect, the tsetse fly, which carries trypanosomiasis (sleeping sickness) in Africa. This prompts the question whether a more complete understanding of the visual systems of disease causing insects and pests would allow us to extend this approach to other species. By applying modern techniques and insight from a different discipline, Ecology of vision, to insect pest control, we have the opportunity to better understand key visual cues, improve trap design and ultimately reduce crop damage and the incidence of disease.
