Scientists find that mosquitoes can be trained

A new experiment has revealed that mosquitoes are able to remember when a person tries to swat them.
It turns out that disease-carrying mosquitoes possess the remarkable ability to associate a person's unique scent with any near-death experiences they may have had while attempting to feed on them.

As such, if a person attempts to swat a mosquito and misses, the insect will remember that this happened and make a point to steer clear of them for the foreseeable future.

To test this effect in a laboratory setting, scientists exposed mosquitoes to a human scent and then used a special mechanism to emulate the vibrations the insects might feel after an attempted swat.

The results indicated that the mosquitoes chose to avoid that particular scent for up to 24 hours - making the technique just as effective as using an over-the-counter repellent spray.

When the team repeated the experiment with the insects' dopamine channels disabled however, this learning behavior was entirely absent and they simply flew straight back to the same target.

"That learning ability makes them incredibly flexible," said neuroecologist Jeff Riffell.

"It means they can learn associations about who is more defensive and who isn't, and if we can prevent that, they'll never learn and can be swatted away way more effectively."

Translation: one shot, one kill. Make it count.

This isn't a surprise. Have you ever noticed that the longer you try to hunt down and swat a fly, the harder it gets because they quit landing on easy to swat places?

Hum, in my experience if you swat a skeeter, they come back and go to your back or foot. They sneak instead of coming right at you but they still come after you.

Yes and they hide if you pick up a magazine and roll it up or pick up a swatter. I think every creature is smarter than we think!
