When it comes to mosquitoes, then a question definitely arises in the mind that how do they target humans. In a research, scientists have tried to find out the answer to this question.
New Delhi: With the increase in heat, the outbreak of mosquitoes has also started. Along with this, the fear of diseases caused by mosquito bites is also increasing. Mosquitoes make people sick on a large scale every year. Campaigns are also run to eliminate mosquitoes, but getting rid of them completely seems impossible. Everyone knows that only female mosquitoes suck blood, male mosquitoes do not. In such a situation, the question is inevitable that how does the female mosquito decide whose blood is to be sucked?
Detects humans with CO2
The answer to this question has been found in a research. Scientists doing research said that the female mosquito needs both smell and sight to locate its prey. For example, we exhale carbon dioxide (CO2), which has a distinct odor. The female mosquito smells this smell and reaches near the human being and then she uses her eyesight to make them prey.
Scientists told that female mosquitoes have the ability to smell the smell from 100 feet away. The amount of air we exhale in a second is 5% of carbon dioxide. On smelling it, the female mosquito flies rapidly towards the human. Research has also found that mosquitoes are more attracted to circling things, but less than carbon dioxide.
This is how the whereabouts are known
According to experts, female mosquitoes find us because they are able to recognize different components of human smell. When mosquitoes come near us with the help of these smells, then they come to know about our whereabouts by the heat of our body. Scientists say that if the ability to smell in female mosquitoes is eliminated, then we can avoid mosquito bites.
loss of sense of smell
If mosquitoes do not bite humans, then diseases caused by them such as malaria, Zika virus and dengue etc. will also be avoided. However, female mosquitoes do not recognize us only because of their ability to smell, so they can be avoided by attacking their other abilities of recognition. Scientists say that, therefore, efforts will have to be made to eliminate the ability to smell in female mosquitoes.
