16-Why do mosquitoes bite some people more than others?
The characteristics the people have which make more attractive for the
mosquitoes are:
Blood Type
The mosquitoes bites us to harvest proteins from our blood research
shows that they find blood types more appetizing than others. One study found that mosquitoes prefer people with Type O blood,after the people with
Type B and finally with Type A. Additionally, based on other studies, about 85
percent of people secrete a chemical signal through their skin that indicates
which blood type they have, while 15 percent do not, and mosquitoes are also
more attracted to secretors than non secretors regardless of which type they
are.
Carbon Dioxide:
Other
reason why mosquitoes bites more people than others is by smelling the carbon
dioxide emitted in their breath. They use an organ called a maxillary palp to do this, and can detect carbon dioxide
from as far as 164 feet away. As a result, people who simply exhale more of the
gas over time generally, larger people have been shown to attract more
mosquitoes than others. This is one of the reasons why children get bit less
often than adults.
Exercise and
Metabolism
In
addition to carbon dioxide, mosquitoes find victims at closer range by smelling
the lactic acid, uric acid, ammonia and other substances expelled via their
sweat, and are also attracted to people with higher body temperatures. Genetic
factors influence the amount of uric acid and other substances naturally
emitted by each person, making some people more easily found by mosquitos than
others.
