Bees are being trained to do the job of sniffer dogs.
And they could be ready to get to work in five years, saving many people’s lives.
Dr Ross Gillanders, a researcher at the University of St Andrews in Scotland, UK, has been training the bees as part of a project funded by an international organisation called NATO*.
By using sugar water as a reward, the researchers have been teaching bees to recognise the smell of explosives as though it was nectar from a flower.
The bees can detect the smell of explosives, which are used to make bombs.
“At the moment we know they can detect the landmines from about 100m distance but that should go up to kilometres. It should happen immediately once they’re trained and released,” Dr Gillanders said.
Landmines are a type of bomb hidden just below the surface of the ground, so that a person walking or a car driving on it sets it off. When landmines are used in wars, the land is not safe for people to return to after the war is over until all the landmines have been cleared.
In the trials, as soon as the bees are sent out of the hive they settle almost instantly on the spot where a landmine is.
Dr Gillanders explained: “Bees have an advantage in that they cannot accidentally set off landmines and can cover ground not readily accessible* for dogs.”
When the bees find the explosives but no reward of nectar they quickly realise they have been fooled and stop detecting the explosives.
“They get used to it so they realise after a couple of days that they have been hoodwinked*. Every few days you have to retrain them but hopefully by that time they have found the explosives.”
There has been a similar trial of bees detecting explosives in the US.
Bees can also be trained to sniff out drugs, chemicals and radioactive substances.
Dr Gillander works in a team with a scientist who used bees to map an area around the Chernobyl Nuclear Power Plant in the Ukrainian SSR, where the worst nuclear accident in history occurred in 1986 and contaminated* the area with radioactive substances, which are very dangerous for people and animals.
The bees are sent to the contaminated area and the scientists can test the contamination levels in the pollen they return with.
Training and keeping bees is quicker and cheaper than training dogs. They are considered at least as sensitive as dogs, and dogs are known to underperform when poorly treated.
Dr Gillanders admitted that a drawback of working with the bees is that bees can sting you. During one field trial he was left with 20 stings on an ankle that was not covered by his beekeeping suit.
He said: “They seemed to know where to go for.
“It was the only part that was exposed.”

1. Bees v Dogs
Pick a side: bees or dogs? Then pretend you are an explosive detecting member of this species and write a compelling argument about why you should be used in the field instead of your competitor. Your argument needs to highlight your strengths and point out your opponent’s weaknesses. You will find information to help with this task in the news article and should be able to think of others that are not mentioned.
