New research shows how color helps stop mosquitoes


Mosquito bites are an unfortunate necessity during the summer — or is it? Scientists have recently discovered that mosquitoes are attracted to some colors more than others. This can be useful for those who are trying to avoid itchy bites.

The studyIt turned out to be a gas that humans exhale after a common type of mosquito, released on Friday, smells CO2. They decided to land on some colored dots, but ignored others.

“Imagine you’re on the sidewalk and smell of pie crust and cinnamon,” said Jeffrey Rifer, senior author of biology at the University of Washington. Press release We will announce the research results. “It’s probably a sign that there’s a bakery nearby, and you might start looking for it. Here, we’re looking for mosquitoes after sniffing their version of the bakery. I started learning the elements. “

The research team placed dots of different colors on the bottom of the chamber and sprayed them with CO2. (Without CO2, mosquitoes ignored everything.) They found that mosquitoes were most attracted to red, orange, black, and cyan.

They also found that mosquitoes ignore green, purple, blue and white. When the researchers wore green gloves and inserted their hands into the chamber, the mosquitoes ignored the CO2 spray, if any.

Unfortunately, avoiding mosquitoes is not as easy as choosing the right color for your clothes. Researchers said that human skin emits a bright red-orange “signal” to mosquitoes, which is difficult to completely hide.

“I used to say that there are three main clues that attract mosquitoes: breathing, sweat and skin temperature,” Rifer said. “We found a fourth clue. It’s the red color you see not only in your clothes, but in everyone’s skin. Your skin tone doesn’t matter. We’re all strong red. I’m giving off a sign. “

Studies have shown that mosquitoes seem to prefer a particular color, but it has not been measured whether wearing a color such as green or purple helps to stop the creature. But Riffel said wearing clothes that avoid the most attractive colors can prove to be another way to reduce bites.

Researchers also hope that their findings will help design better repellents, bug traps, and other ways to repel biting insects.
