Is Biodiversity Why Mosquitoes Bite Some People More Than Others?

Astonishingly, research suggests mosquitos are repelled by certain skin microbiome compositions

A study from 2011 first described how individuals who are very attractive to mosquitos (An. gambiae s.s.) have a low biodiversity of the skin microbiome. 

In addition, it identified specific bacteria genera associated with attractiveness to mosquitos.

This finding is elaborated on in a 2017 work, where different types of mosquito were found to be more attracted to people who have a skin microbiome that contains a certain amount of specific species of microbe. 

"The human skin microbiome produces volatiles that affect mosquito behavior."

The finding, backed up by a study in 2022, describes how microbes on our skin produce volatile compounds that determine whether or not a mosquito decides to bite a human. 

To conclude, increasing the biodiversity of the skin microbiome could help protect you against being bitten by mosquitos. This finding is interesting because a low biodiversity on the skin has been associated with a huge array of other skin problems.
