A sniffer bee is a trained honeybee
Research into honeybees (Apis mellifera) started in the 1960’s. The researchers were interested mainly in understanding the foraging behaviour of honeybees. These tiny creatures were shown to learn almost any odours and have subsequently inspired numerous researchers to explore the practical application of Sniffer Bees. In early 2004, DARPA (Defence Advanced Research Projects Agency) funded a project to use the honeybees for explosives detection. They discovered that honeybees can detect TNT at parts-per-trillion (ppt) level. That is as sensitive as or better than dogs. It was encouraging but not enough to persuade the military to adopt them in a battlefield. The main concern is the logistics and practicality of using bees in the field – until the invention of Inscentinel patented BeeSensorSystem.
