Some unfortunate people are irresistible to mosquitoes, while the scent of some lucky individuals drives the blood-suckers away. Now the smelly chemicals from the sweat of these lucky people have been identified by researchers, who are testing its effectiveness as a natural mosquito repellent.

Everybody produces a mixture of odorous chemicals in their sweat, some of which attract biting insects, such as lactic acid. But people who do not get bitten also produce smelly chemicals that appear to mask the scent of the attractive chemicals.

This masking can offer an effective camouflage against mosquitoes, explains James Logan, who carried out the research with John Pickett at Rothamsted Research in Harpenden, and colleagues at the University of Aberdeen, both in the UK.

These helpful chemicals probably occur naturally in everybody’s sweat but some people have a much higher ratio than others, Logan says.

What is more, the same benign sweat chemicals that repel the tropical mosquitoes Aedes aegypti – responsible for spreading yellow fever throughout Africa and South America – appear also to disgust the persistent biting midge that terrorises the west coast of Scotland, the researchers discovered.
Sweat collectors

Logan constructed a Y-shaped chamber and wafted the scent of different people down two of the branches by getting volunteers to place their hands at the ends. The blood-sucking insects flew from the thin end of the "Y" towards the human hand they preferred.

He then analysed the body odour of those individuals found to be unattractive by sealing their bodies in a foil sack, tied under the chin, and collecting and distilling the sweat that poured off them.

The most potent repellent chemical were then isolated by strapping miniature electrodes to the antennae of female mosquitoes and checking their responses to specific compounds. Logan will not divulge the names of the chemicals until they are patented. But he does reveal that although the scent of the chemicals is normally undetectable by humans, they have a fruity smell when highly concentrated.
Food additive

“It’s very exciting," Logan told New Scientist, "because these are totally natural chemicals with an effectiveness that compares favourably to harsher chemicals such as DEET, which is the best repellent available but has unwanted effects, including dissolving plastics.”

A key chemical identified by Logan as a repellent is also "a natural food additive, so has proven safety", he says. "And because it can be made by plants, it may one day be possible to mass produce it cheaply.”

The repellent is currently being trialled with 16 volunteers in Africa. Meanwhile, the researchers are testing the repellent against other biting insects, including malaria carrying mosquitoes.

The research was presented at the Royal Society Summer Science Exhibition in London, UK, and has been submitted to a leading peer review journal for publication.

I have the same thing. Lived up north for a long time, and every summer I'd have maybe 10 mosquito bites. However, I've never been sure if it was that they didn't bite me at all, or that I just didn't react. It may be that they are biting you, but that you do not have a strong allergic reaction to the bite. That's my theory.

BTW, my sis gets them really bad, and she is a lot darker than me, so whoever said their sister got less bites b/c she is darker... not so. It's not your skin they're after, it's your blood!

Enjoy it either way!

The real reasons may be any of the following:

You are having such germs in the
body, which the mosquitoes are
afraid of.

Your germs can kill them.

You are from a different planet.

May be you look like one of their
lost brother.

May be you are fond of eating
them.

May be they donot want a virus
to get into their body and
work like dengue in them.

May be they donot like the
odour of your body.

Please go to the Institute of
Communicable Diseases.
and get your blood tested.
In case they find that you are
unique, after the tests, they may
declare you as a NATIONAL
PROPERTY and start payiny
you royalty to you.

You may approach the WHO for their
research, and get an Immegration Visa,
for carrying out their research with
your blood. Hand some Salary?
Celebrity? Millions of $ s?
It is exciting. Americans and Europeans
spend several Billions of Dollars
every years on research "HOW TO
PREVENT MOSQUITO BITE"

ALL THE BEST FRIEND. PLEASE REMEMBER ME FOR MY IDEA AND WRITE TO ME IF YOU GO ABROAD.

The smell from the sweat, is what attracts the mosquitoes...
It is said that the salt contents in the sweat is what attracts them.
May be the ingredient that attracts them, is too less in you !
You have to try when no other person is around, and stay amidst mosquitoes to find out if still the fragrance of your sweat does not attract them ! But please take care, now-a-days that chikungunya is widespread, so not worth taking chances !

I have a sister like that and it really drives me crazy as i love the outdoors and if bitten by a mosquito i get deadly sick.The reason for them not biting her is she has a darker complexion than i do.

I used to get bitten a lot until I lived in the area long, and nothing happened. Also, ever since I became a vegetarian I have not been bitten. It's weird, I know, but be thankful we're lucky.

absolutely not buddy. it doesnt depend on the blood group. But it depends on the chemicals released by your skin.. if you get more sweat, then you get bitten with more mosquitoes.

I guess you are always clean and neat
