Question

How do mosquitoes locate human beings to bite?

• A. They have sharp eyes
• B. They use sound to locate humans
• C. They use their sense of smell
• D. None of the above

Answer 1

Answer: (C)

They use their sense of smell

• Many insects, mosquitoes included, are attracted by the odour of the carbon dioxide (CO2) gas that humans and other animals naturally exhale.
• However, mosquitoes can also pick up other cues that signal a human is nearby. They use their vision to spot a host and thermal sensory information to detect body heat.

So, the correct answer is 'They use their sense of smell'.
