Researchers zapped the insects with a small dose of radiation and infected them with a virus-fighting bacterium called Wolbachia.

So researchers intentionally infect males with a strain not found in the area and then release the insects. (Guangzhou Wolbaki Biotech via AP)

Scientists Find New Way To Kill Disease-Carrying Mosquitoes

NEW YORK (AP) — Scientists say they nearly eliminated disease-carrying mosquitoes on two islands in China using a new technique.

But it's not clear whether this will be practical for larger areas or how expensive it'll be.

In the experiment, researchers targeted Asian tiger mosquitoes, invasive white-striped bugs that can spread dengue fever, Zika and other diseases. They used a novel technique that combined exposing the insects to radiation and infecting them with a bacterium.

For 18 weeks in 2016 and 2017, they released male mosquitoes onto two small islands near Guangzhou, China, a region plagued by dengue fever. The number of female mosquitoes that are responsible for disease spread plummeted by 83% to 94% each year, similar to other methods like spraying insecticides and using genetically modified mosquitoes.

Findings appear Wednesday in Nature.
