Reader question: Why do Thai mosquitoes mainly sting foreigners?

As a pensioner I have been living in Thailand for 8 years and I also go, almost the same number of years, on a golf course, 3 times a week, playing 18 holes of golf and I am still being harassed by a certain kind of mosquitoes and almost eaten.

My accompanying Caddy-lady will then have no problems.
I always thought it was because of my blood type. (0- Negative) A blood type that is difficult to obtain in Thailand.

In line with what Jordaan writes. I also notice that my girlfriend and her sisters see when a mosquito has settled not only on their but also on my skin. And often they are quite a distance away from me.

But even when Mrs. Mosquito is still flying, they see her and manage to crush the mosquito between their hands in her hovering flight. I have succeeded 1 time so far.

And the female mosquito does not suck the blood for food, but to lay eggs in water.

Is the white man more likely to be stabbed than his Thai beauty?

Mosquitoes first follow a trail of carbon dioxide. That means that there is a breathing mammal nearby. The closer they get, the more they will be guided by body heat.

A mosquito chooses the victim with the most body heat (= most blood), because then the chance of a tasty meal is greatest.

Many Asians (= actually people from countries where Malaria occurs) are carriers of the genetic abnormality Thalassemia or Sickle Cell Anemia.
As a result, many Thai suffer from chronic anemia to a greater or lesser extent.

People with this gene abnormality survive better in Malaria countries, so Thailand has a lot of people with this gene abnormality.

People from non-malaria countries are therefore more often bitten by mosquitoes.

Read these articles carefully if you want to have children with your beautiful Thai.
Then have yourself tested for this gene abnormality.
If 2 people with this gene abnormality have children, these children can become fatally ill!!

After 20 years of Thailand, I'm out for myself / the longer I stay, the less the mosquitoes like me. As Tino says, you get stung a lot in the first weeks like me, so at some point you have so much "mosquito poison" in your blood, that this will also become your defense! I myself experience this again and again, after 3 weeks the mosquitoes don't like me anymore!!!

Just to reassure men who are worried about their Thai partner.
The disease that Jos mentions is more common in people around the Mediterranean than in Asia.

Anyone can be a carrier of thalassemia genes. On average, 3% of the world's population has a thalassemia gene (and therefore a thalassemia trait). The chance of having thalassemia genes varies depending on your family origin. Thalassemia is more common in people of Mediterranean, Asian, or African origin.

For example, beta-thalassemia genes are carried by: 1 in 7 Greek Cypriots, 1 in 12 Turks, 1 in 20 Asians, 1 in 20-50 Africans and Afro-Caribbeans (depending on which part of Africa your family comes from) and 1 in 1000 people of Northern European origin.
