Researchers from the University of Washington believe yellow fever mosquitoes are attracted to certain colors—including red, orange, black and cyan.
A new study shows that mosquitoes are attracted to certain colors — including red, orange, black and cyan — while ignoring other colors like green, purple, blue and white.in Nature Communications. They hope their data will explain how mosquitoes find hosts, especially since human skin emits a strong red-orange "signal" to their eyes.
Researchers studied the behavior of the female yellow fever mosquitoes, also known as Aedes aegypti. They presented the insects with different types of visual and scent cues. Only female mosquitoes drink blood. Researchers also tracked individual mosquitoes in a chamber, sprayed specific odors and presented different visual patterns such as a colored dot or a tasty human hand.Senate Majority Leader Chuck Schumer announced Sunday a new push to zap one of the worst mosquito seasons in New York.
The findings revealed that without an odor, mosquitoes ignored a dot at the bottom of the chamber, regardless of the color. After carbon dioxide was sprayed into the chamber, mosquitoes continued to ignore that dot if it was green, blue or purple in color. However, they would fly towards the dot if it was red, orange, black or cyan.
While humans can’t smell carbon dioxide, the gas that humans and other animals exhale with each breath, mosquitoes can."Imagine you’re on a sidewalk and you smell pie crust and cinnamon,"
