Honeybees have an extraordinary sense of smell that allows them to detect a wide range of substances, including explosives. Researchers have explored the possibility of using bees as biosensors to detect explosives in various settings, such as airports or military bases.
The idea is based on conditioning bees to associate the smell of explosives with a food reward. When exposed to the scent of explosives, trained bees can exhibit a specific response, such as extending their proboscis (tongue) in anticipation of a reward. By monitoring the bees’ response, it’s possible to detect the presence of explosives in the environment.
