Scientists at Los Alamos National Laboratory have developed a method for training the common honey bee to detect the explosives used in bombs. Based on knowledge of bee biology, the new techniques could become a leading tool in the fight against the use of improvised explosive devices, or IEDs, which present a critical vulnerability for American military troops abroad and is an emerging danger for civilians worldwide.
By studying bee behaviour and testing and improving on technologies already on the market, Los Alamos scientists developed methods to harness the honey bee's exceptional olfactory sense where the bees' natural reaction to nectar, a proboscis extension reflex (sticking out their tongue), could be used to record an unmistakable response to a scent. Using Pavlovian training techniques common to bee research, they trained bees to give a positive detection response, via the proboscis extension reflex, when they were exposed to vapours from TNT, C4, TATP explosives and propellants.
