Mosquitoes have an extraordinary ability to target humans far away and fly

straight

to their unprotected skin. Regrettably，mosquitoes can do more

than cause an itchy(发痒的）wound. Some mosquitoes spread several serious

diseases，including Dengue，yellow fever and malaria. Over one million people worldwide

year. New research

die from these diseases

each

now shows how mosquitoes choose who to bite.

Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas，which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.

But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects，with even smaller brains，use three senses to find a blood meal. Michael Dickinson’s team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.

Then，the scientists placed dark floor and walls of

objects on the lighter colored

the tunnel. Mr Dickinson said，at first，the mosquitoes

showed no interest in the objects at all.

“What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO2，they change their behavior quite obvi ously and now would become attracted to these little visual blobs (斑点）.”

This suggested to the researchers that a mosquito’s sense of smell is more important in the search for human or animal，they also

food. Once mosquitoes catch a smell of follow visual signals.
