If an elephant becomes a problem, humans may kill it.

So local people and conservationists are trying to find better ways to keep

elephants away from sensitive places. Now, researchers think they have a good tool to deter elephants,

honeybee pheromones. Elephants deplore being stung in the trunk. It's an extremely sensitive

organ that they have, you know, imagine being stung in your nose by a bee and multiply

that by a few thousand times. Mark Wright, a professor of entomology at the University of Hawaii at

Manoa. Kenyan farmers already know that if they hang live beehives around their farms, they will

repel elephants. The problem is logistically, how do you manage hundreds or thousands of hives if you have a huge area to protect?

And then the idea came up to you to look at the alarm pheromones, which are chemicals that the bees
