Mosquitoes Use a Combination of Our Body Heat, CO2 and Body Sweat to Target Us for a Meal

Mosquitoes can only find us when our body heat, odor and emitted carbon-dioxide are present

Researchers already know that mosquitoes target us by tracking our body heat and the carbon-dioxide emitted from our breath. Now they have also found out that mosquitoes locate us by detecting certain chemicals from our body sweats. A study published in the journal Current Biology states the offensive flying insects have an olfactory receptor in their antennae for detecting humans for a meal.

Mosquitoes are blood-suckers, and they transmit malaria, Zika virus and dengue among other tropical diseases. Understanding how they track us for a blood-meal is essential to developing protective techniques to foil their attacks.

Mosquitoes can detect human body heat from a distance, and they zero in on the heat signature to find humans and animals for a bite. They also detect the carbon-dioxide exhaled from human nostrils and emitted via the ear to know human bloodmeals are available for consumption. Having now perfected their sense of smell to detect the lactic acid and other chemicals in human sweat, mosquitoes have now evolved into a formidable human enemy.

Mosquitoes Attack Humans When Body Sweat, Body Odor and CO2 Are Emitted From People

Mathew DeGennaro of the Florida International University in Miami said it is exciting to know that mosquitoes have a receptor for human sweat. This they use to sense human odor and converge for blood.

The olfactory receptor is called Ir8a. Scientists found that blocking the function of this receptor made it impossible for mosquitoes to detect human sweat. During lab studies, researchers asked participants to place their hands on a device called an olfactometer. Mosquitoes can detect the olfactometer and the humans around it with ease. After genetically disabling the olfactory receptor in mosquitoes, the researchers found mosquitoes lost interest in detecting human presense.

Even after putting clothing worn by people during the day into the olfactometer, mutant mosquitoes found it hard to detect the sweat on the clothes. But normal mosquitoes did. Jeff Riffell, a biologist at the University of Washington, said it might make sense to create a spray perfume that masks human odor and throw mosquitoes off our trail.

However, disabling the ability of mosquitoes to sense human body odor does not entirely incapicitate them from detecting people – since they rely on other capabilities to still find their food.

An Effective and Lasting Solution Is Required To Destroy the Abilities of Mosquitoes to Find People

Larry Zwiebel, a biologist at Vanderbilt University, said mosquitoes are human-seeking machines because they possess an overlapping sensory system that goes beyond smell. He demonstrated that the insects can only detect the lactic acid in human sweat in the presence of carbon-dioxide and emitted heat.

“So it shows that in order for this process to really work effectively, and at its highest level, the mosquito wants to sense carbon dioxide, and that information makes the lactic acid information more valuable to the mosquito — more usable,” Zwiebel said.

According to him, when mosquitoes sense the combined presence of human odor, body heat and emitted CO2, they recieve the strongest degree of impulse to zero in on people and animal targets. Until a better and effective way is developed to permanently defeat mosquitoes in our environments, a powerful repellent that confuses their human-detection system might be a temporary solution.
