We know a lot about mosquito preferences up close, but how do mosquitoes find us from up to a hundred meters away? Using an ice-rink-sized outdoor testing arena in Zambia, researchers found that human body odor is critical for mosquito host-seeking behavior over long distances. The team also identified specific airborne body-odor components that might explain why some people are more attractive to mosquitoes than others. The work appears May 19 in the journal Current Biology.
