The findings mean that you can choose what to wear to reduce(减少) your chances of being bitten, but there’s little you can do about your skin. This is because everyone’s skin gives off a strong red signal. “I used to say there were three main things that attract mosquitoes—our breath, sweat(汗水) and the temperature of our skin,” said Jeffrey Riffell, a senior researcher of the study. “In this study, we found a fourth one: the color red. It can be found not only on your clothes, but also in everyone’s skin. We are all giving off a strong red signal no matter our skin is light or dark.” Researchers found that when mosquitoes find CO2 from our breath, they then look for certain colors—including red, orange and black—to find their meal of blood. But they are not interested in colors such as green, purple, blue and white. “Mosquitoes seem to use smells to help them know what is nearby,” Riffell said. “Imagine you’re on a street and you smell pie,” Riffell said.“That’s probably a sign that there’s a cake shop nearby, and you might start looking around for it.” Knowing what colors mosquitoes like or dislike may lead to better methods to protect us from mosquitoes. According to the researchers, further study is needed to learn how other things mosquitoes can see or smell help guide them to their goals.
