Scientists have created a new app designed to identify dangerous mosquitoes.The app,called Abuzz,is aimed at helping fight major diseases spread by mosquitoes,which kill hundreds of thousands of people each year.

Anyone with a mobile phone could use the app to identify mosquitoes.If they see a mosquito around,they just take out the phone,open the app,point their phone towards the mosquito and hit the record button.Then,when the mosquitoflapsits wings and starts flying around,it makes that annoyingbuzzingnoise.That noise is what gets recorded by the Abuzz app.

Many diseases that mosquitoes carry do not have cures orvaccines.So,targeting the flying insects is the best way to control them and the most important step is to know where the mosquitoes are.Out of about 3,500 different mosquito species,only about 40 are dangerous to humans.

The goal of the project was to find out whether the mosquitoes are just an annoyance or whether they are possibly dangerous.To find out,the researchers decided to listen.When moving their wings up and down,mosquitoes produce buzzing sounds.But each kind of mosquito makes a somewhat different buzzing noise.The app records these sounds.Users of the app can get an answer by recording as little as one or two seconds of the buzzing sound.The app compares this recording to a collection of other recordings.It then predicts which species of mosquito it is most likely to be.

Billions of people around the world can use this tool with their phones.So,the researchers say they will be able to monitor mosquitoes on a much larger basis than in the past.By searching mosquito information worldwide,the app can help build maps of where dangerous mosquitoes are.This can help scientists and health officials identify areas where disease is likely to break out and where to target mosquito control.Therefore,this kind of widespread community effort can be an important step in fighting mosquito-causing diseases.
