How Insects Track Odors by Navigating Microscale Winds

Tuesday, May 30, 2023 - 11:02 in Biology & Nature

Insects use odor plumes -- which travel like smoke and form when the wind blows odor molecules from their source -- to track down sources such as flowers or pheromones. But wind tunnels are typically unable to replicate realistic outdoor wind conditions. In Physics of Fluids, by AIP Publishing, University of Nevada at Reno researchers decided to explore microscale wind conditions in various outdoor environments to better understand what flying insects might experience while tracking odor plumes.
