Visual-Olfactory Integration in the Human Disease Vector Mosquito Aedes aegypti (Current Biology)

When mosquitoes encounter CO2, they become attracted to dark, visual objects. Using tethered mosquitoes and calcium imaging experiments, Vinauger, Van Breugel et al. find that CO2 modulates lobula neuropil responses to discrete visual stimuli. This modulation may facilitate host tracking by navigating mosquitoes.
