Significance Tsetse flies pose a major threat to the health and economy of sub-Saharan Africa. They transmit trypanosomes that cause African sleeping sickness in humans and a disease called nagana in livestock. Tsetse find their hosts in large part through olfactory cues, but little is known about the cellular basis of olfaction in these flies. We carried out a systematic physiological analysis of olfactory response in the tsetse antenna. We identified 7 classes of olfactory sensilla that respond to human or animal odors, CO 2 , pheromones, and a tsetse repellent. The functional organization of the tsetse fly is strikingly different from that of the fruit fly Drosophila . This study may be useful in devising new means of controlling tsetse.
