But no matter what you wear, your skin emits the right wavelength. 🦟 engineering
A group of scientists from the Unversity of Washington has found out that mosquitoes are usually flying towards specific colors such as red, orange, black, and cyan, after detecting a telltale gas from our breaths. And the little creatures often ignore colors like green, purple, blue, and white.
The results of the study, published on February 4 in Nature Communications, reveal how the mosquito’s sense of smell — known as olfaction — influences how the mosquito responds to visual cues. Knowing which colors attract hungry mosquitoes, and which ones do not, can help design better repellants, traps, and other methods to keep mosquitoes at bay.
In the absence of an odor stimulus, mosquitoes largely ignored a dot at the bottom of the chamber, regardless of color. After a spritz of CO2 into the chamber, mosquitos continued to ignore the dot if it was green, blue, or purple in color. But if the dot was red, orange, black, or cyan, mosquitoes would fly toward it.
We, humans, see color in different wavelengths of light, and the team currently does not know whether the mosquitoes perceive color as we do. But according to the experiments, mosquitoes prefer longer wavelengths of light upon smelling CO2.
