Volatile Organic Compounds Emitters

You emit volatile organic compounds (VOCs) from your skin, and these chemical signals play a crucial role in attracting mosquitoes.

Human skin is home to a diverse range of bacterial and fungal communities, which break down amino acids and other nutrients to produce VOCs.

These compounds can vary in type and amount depending on factors such as your diet, hygiene, and health status.

As a result, your skin emits a unique blend of VOCs that can be detected by mosquitoes.

Some people’s skin may produce more attractive VOCs than others, making them more susceptible to mosquito bites.

Researchers have identified specific VOCs, such as lactic acid and acetone, that are particularly attractive to mosquitoes.

By understanding how your skin emits VOCs, scientists can develop new strategies to prevent mosquito-borne diseases.

For example, they might create insect repellents that target these specific compounds or develop clothing that reduces VOC emissions.

Microbe-Generated Chemical Signals

By analyzing the chemical signals generated by microbes on your skin, researchers have discovered that certain volatiles in body odor and metabolic pathways are associated with individuals who are poorly attracted to mosquitoes.

Your skin microbiome, comprising trillions of bacteria, plays a vital role in this process. These microbes break down carbohydrates, fatty acids, and peptides into volatiles that mosquitoes can differentiate.

Notably, researchers found that Staphylococcus 2 ASVs were four times more abundant in the highly-attractive group compared to the poorly-attractive group. On the other hand, propanoic pathways were enriched in the poorly attractive participants compared to those found to be highly attractive.

These differences in skin microbiome composition between poorly- and highly attractive groups suggest that the bacteria on your skin influence mosquito attraction.

Skin Defenses Against Mosquitoes

Your skin has developed various defense mechanisms to counter mosquito attraction, including the production of antimicrobial peptides that regulate the growth of skin microbes and reduce their numbers directly.

These peptides, such as cathelicidins, help control the proliferation of skin bacteria, making it less attractive to mosquitoes. However, certain conditions like atopic dermatitis can suppress cathelicidin production, making people more susceptible to mosquito attraction.

Vitamin D also plays a vital role in controlling cathelicidin production, and deficiencies in vitamin D may lead to increased mosquito attraction.

Additionally, the natural acidity of the skin, maintained by lactic acid in sweat and produced by skin bacteria, helps defend against mosquitoes. Damaged skin can disrupt this balance, allowing nonpathogenic bacteria to become pathogenic and making the skin more attractive to mosquitoes.

It’s clear that your skin is constantly working to defend against mosquito attraction, and understanding these mechanisms can help people take steps to reduce their attractiveness to these pesky insects.
