Hymenoptera training
Sniffer bees or sniffer wasps are insects in the order Hymenoptera that can be trained to perform a variety of tasks to detect substances such as explosive materials or illegal drugs, as well as some human and plant diseases. The sensitivity of the olfactory senses of bees and wasps in particular has been shown to rival the abilities of sniffer dogs, though they can only be trained to detect a single scent each.
