Human Scent is even sweeter for Mosquitoes


I stumbled upon this article and i found it so interesting. so i decided to share it with all my viewers. i know you are curious to get to understand what i mean, so let me share,it with you all.

People smell yummy to mosquitoes, infact so yummy that our scents is a big way the insect track us down.
Mosquitoes are more attracted to human odours when they are infected with malaria parasite, scientist reported Wednesday in the journal PLOS ONE.
Entomologists(zoologist who focuses on insects) at the london school of Hygiene and Tropical medicine gave malaria transmitting mosquitoes two places to land; a clean nylon stocking and one worn for 20 hours.

All the mosquitoes gravitated more towards the dirty sock than the fresh one. but the bugs infected with the malaria parasite landed on the smelly nylon more frequently, and while they were there, the parasites-possessed bugs were more likely to try and bite the stocking than the malaria-free insects.
Scientists have known for a decades that the malaria vectorAnopheles gambaie is highly attracted to people. In fact, these ladies – it's only the females that bite us — actually prefer to feast on humans than many other animals. They even 

have a strong aversion to cow odor.
So what's in our bouquet that makes us so alluring to mosquitoes?
Human skin emits over 350 different odor molecules. The An. gambaie mosquitoes have odour receptors in their antennae specifically built to detect a handful of these scents.
 Scents or no scents this insect will definitely attack and suck..thats my own say.
