The likelihood of being bitten by mosquitoes could be down to genes that control our body odour, a preliminary study in Plos One suggests.

Researchers tested pairs of identical and non-identical twins to see how attractive they were to mosquitoes.

Identical twins were more likely to have similar levels of attractiveness - suggesting shared genetic factors were at play. The "intriguing" results must now be assessed in larger trials, experts say.

Researchers have long tried to understand what drives mosquitoes to bite certain people more than others. Recent work shows the insects may be lured to their victims by body odour. And anecdotal reports suggest some relatives are just as likely to be bitten as each other.

Scientists from the UK and US wanted to find out whether genes were behind this phenomenon. To test their theory they enlisted 19 non-identical and 18 identical pairs of twins in a pilot study.

Mosquitoes seem to have a preference for which humans they bite

Identical and non-identical female twins took part in the study. In a series of experiments each twin placed one hand at an end of a Y-shaped wind tunnel as air was pumped through, carrying odour with it. Swarms of mosquitoes were then released and moved towards or away from each twin's hand.

For identical twins - who share much of their genetic material - there was an even distribution of mosquitoes in both sections. This suggests the insects did not prefer the odour of one hand more than the other.

In contrast, results for the non identical twins - who share fewer genes - were more varied.
Researchers say their works suggests attractiveness to mosquitoes could be caused by inherited body odour genes.

Their next step is to uncover which specific genes may be involved.

Further research is now under way.

Interesting.....though I guess more studies needed.

If we could synthesize the odours using genetic based methods....we could have an effective mosquito repellent cream at last.

Make they use our very own benin mosquito do the research

Yeah, a brilliant study which might lead to varieties of mosquito repellant. However, total eradication of mosquitoes is the desired solution.
