Boffins down in Australia are attempting to use the odour receptors on insects to build a 'cybernose'. They think that the power that insects have will detect aromas in minute quantities. If they manage to do this the aim is to detect wine faults - brettanomyces (smells like shit), cork taint and other faults.
Wasps - well they had to have some use - have the ability to detect individual smells at concentrations of one part per trillion. Each insect has about 60 different odour receptor proteins and by using electrical signals the inventors hope to mimick an insects behaviour.
