QI - Sniffer Bees

"Stephen Fry, Alan Davies, Jimmy Carr, Johnny Vegas and Sarah Millican, chat about the use of sniffer Bees instead of Sniffer Dogs in detection of criminal activity." - YouTube

Like so much of QI, it seems like they're being intellectually sloppy. They offer some evidence that bees are easier to TRAIN, but do they actually detect smells at lower concentrations? It seems unlikely to me. A dog simply has a much, much larger sensor than a bee.

Inscentinel claim that their studies show the bees to be at least as good as sniffer dogs:

> For most compounds bees are much more sensitive than humans, and our studies indicate that they are at least as good as sniffer dogs. They can for instance detect parts per trillion concentrations of explosive material such as TNT

Note also that they don't just use a single bee -- they have a group of them in cassettes in the detector boxes.

Wikipedia has some interesting information here about other things that wasps and bees have been used to detect (e.g. certain cancers, by smelling breath):
