age old question on why some ppl get bitten while some dont! and i’m one of the lucky ones! i can go into the jungle and come out with only 1 or 2 bites, while my friend gets her neck, arms, back of knee and calf bitten……..
mozzies are attracted to the odorants emitted by our skin. which are chemical markers, and scientists say are the docking platform for the proteins found on the antennas of the mozzies..
other things that attract mozzies are the amount of carbon dioxide in our breath (the more the merrier for mozzies), pregnant women (maybe cos they exhale more carbon dioxide), body temperature (slight increase), alcohol (cos it increases body temp), lactic acid and cholesterol on skin, and odorants based on blood type.
for every blood group, there are those who emit these chemical markers (secretors) and there are those who dont (non-secretors). scientists found that mozzies were attracted to those who emit the markers more than those who dont emit the markers.
among the blood group, apparently type O blood people have a higher chance of feeding mozzies, while type A blood had the least.
type O secretors have a higher chance compared to type O non-secretors and type A secretors. but scientists also found that between Type O secretors and type A non-secretors, these mozzies have no preferrences. (darn puzzling!)
other than secretors, the other theory that scientists are still researching on are the correlation between the amt of carbon dioxide and mozzie landings. so seems that since adults and pregnant ppl get bitten more, the hypothesis is that active ppl get bitten more too. which some ppl have acknowledged that 1 twin playing actively will get bitten more than the other twin who is sitting down.
either way, im fine cos i dont get bitten so much, even without insect repellants…
