high-altitude mosquito migration study: balloon prep

In a muddy, grassy field, several people stand on a blue tarp while examining the underside of a large white helium balloon.

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.)
