It is hard to escape a female mosquito since she will hunt down any human by monitoring our CO2 exhalations, body heat, and odor. However, some of us are clearly “mosquito magnets” who receive an excessive number of bites. Popular suggestions for why someone could be a favorite snack include blood type, blood sugar level, eating garlic or bananas, being a lady, and being a youngster.
Skin microbiota-related individual odor differences. Mosquitoes may be drawn to the intense scent produced by fatty acids coming from the skin.
The correlation between having a lot of these fatty acids on your skin and attracting mosquitoes is significant.
Large concentrations of these fatty acids on your skin are strongly linked to becoming a mosquito magnet.
Mosquito magnets created considerably more carboxylic acids than the less attractive individual. These ingredients, which are found in sebum, are utilized by microorganisms on our skin to create our distinctive human body odor.
Mosquitoes create two primary types of smells that they use to identify humans: IR and Orco receptors. Or mutants kept their attraction to humans and their capacity to discriminate between mosquito magnets and low attractors, whereas IR mutants lost their attraction to humans to varying degrees but kept their ability to locate us.
The female mosquito needs it as a backup to survive and procreate. She cannot do either without blood. Because of these variations in the skin chemistry of the targets she pursues, “she has a backup plan, a backup plan, and a backup plan.”
It’s hard to imagine a day when humans aren’t the most popular dish on the menu given how seemingly unbreakable the mosquito smell tracker is. Manipulating our skin’s microbiomes is one option, though.
It’s likely that applying sebum and skin bacteria from the skin of a subject who has a low attraction, like Subject 19, to a subject who has great appeal, like Subject 33, might have the effect of hiding mosquitoes.
Someone like Subject 33 may become Subject 19 by undergoing a food intervention or microbiome intervention in which skin-implantable microorganisms with the capacity to alter their interactions with sebum are used. However, all of it is highly theoretical.
