New App Records Sound to Identify Dangerous Mosquitoes

Scientists have created a new app designed to identify dangerous mosquitoes based on sounds the insects make. The app, called Abuzz, is aimed at helping fight major diseases spread by mosquitoes. The diseases – such as malaria, dengue fever and yellow fever – kill hundreds of thousands of people each year.

Haripriya Vaidehi Narayanan is one of the researchers who helped develop the app. She began work on the project as a graduate student at Stanford University. She is now with the Department of Immunology at the University of California, Los Angeles.

Narayanan told VOA that anyone with a mobile phone could use the app to identify mosquitoes. “If they see a mosquito around, they just open the phone, open up the app, point their phone towards the mosquito and hit the record button,” she said.

“Then, when the mosquito flaps its wings and starts flying around, it makes that noise, that annoying buzzing noise. That noise is what gets recorded by the Abuzz app,” she added.

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 crowdsourcing 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.

Manu Prakash, a professor of bioengineering at Stanford University, said he believes this kind of widespread community effort can be an important step in fighting mosquito-causing diseases.

The development team is expected to release the Abuzz app to the public in the coming months.
