A Scientist Explains Why Mosquitoes Bite Some People More Than Others

• https://www.sciencealert.com, RICHARD HALFPENNY

But Aedes aegypti and Anopheles gambiae are well known for their preference for human blood and their role as vectors which transmit disease in humans. Ae. aegypti has been linked to zika and dengue, while An. gambiae carries the parasite which causes malaria.

Not only do certain mosquito species show very strong preferences for obtaining their blood meals from humans, they also appear to discriminate between people when choosing their next meal.

Personally, I'm lucky – I don't tend to get bitten much. I've shared rooms with people who end up covered in bites while I escape with only a nibble or two. I'm sure you've noticed something similar, whichever side of the arrangement you might fall.

Although this is only an anecdote, it is backed up by research. So why is it happening? What factors might influence the mosquito's choice?

There are many old wives' tales on the matter, some more plausible than others.

Some think that blood type, having fair skin, being sweaty and even eating foods with garlic or apple cider vinegar can influence biting rates one way or the other.
