Insect vectors of diseases locate their animal hosts through olfaction via largely unknown molecular processes. Here the 'empty neuron' system of genetically engineered Drosophila is used to assign specific odorants to the entire repertoire of olfactory receptors of the malaria vector Anopheles gambiae. The results illuminate ecological and neurobiological differences between mosquitoes and fruitflies and provide new potential molecular targets to boost the struggle against insect–borne diseases.
