When a man is standing in mosquito-infested territory in a light breeze, the mosquitoes will pass him by, but those which enter the downwind cone of his emanations will turn and work upwind to him from as much as 30 feet away, as closely observed by Hocking1 of Aedes dorsalis on the Alberta prairie. When a man is standing in a closed room, the mosquitoes in flight alongside ignore him, but let him lie down and he will activate all those which experience the ascending convection currents above him, as found by Mer et al2 for Anopheles sacharovi in Israel. The photographs obtained by Kellogg and Wright3 for Ae aegypti exposed to a smoke-marked moving cone of warm, moist air show that these avid females proceed upwind to its source by a behavioral response known as anemotaxis, supplemented by klinokinesis on the boundary of the cone that
