6- Pregnancy
some species are more attracted to pregnant women than those who are not. One study in Africa found that pregnant women are more attractive to malaria-carrying mosquitoes as non-pregnant ones; researchers believe it is because of the existence of carbon dioxide – they discovered that women in late pregnancy exhaled 21 percent greater volume of breath than non-pregnant women. They also found that the pregnant women abdomens were 1.26°F hotter, adding to the mosquitoes like-warm-bodies component.
