How one of the oldest natural insecticides keeps mosquitoes away

A new study has identified a scent receptor in mosquitoes that helps them sniff out and avoid trace amounts of pyrethrum, a plant extract used for centuries to repel biting insects. These findings could help researchers develop new broad spectrum repellents to keep a variety of mosquito species at bay, and by extension stop them from biting people and spreading disease.
