high-altitude mosquito migration study: balloon launch

In an open grassy field, a man holds a rope that extends upwards toward a large white balloon floating in the sky about 25 feet above ground.

A series of studies published since 2019 has shown mosquitoes can ride high-altitude winds to travel long distances in Africa. The discovery was enabled by the use of a new research tool: glue-daubed net traps hanging below helium-filled balloons. (Photo courtesy of Harrysone Atieli, Ph.D.)
