Scientists have almost completely destroyed mosquitoes carrying diseases on two islands in China using a new technique but they have not made it clear whether this will be practical for large areas or how expensive it will be.
In the experiment, scientists focused on Asian tiger mosquitoes, invasive insects with white stripes that can spread dengue, physics, and other illness. These are mosquitoes from the Aedes family, very similar to those that spread the same diseases in our region. They have used a new technique that combines exposure to radiation and infects them with bacteria.
For 18 weeks in 2016 and 2017 male mosquitoes were placed on two small islands near Guangzhou, China, a region suffering from dengue fever. The number of female mosquitoes responsible for the spread of diseases fell between 83 and 94 percent each year, a result similar to that achieved by other methods, such as spraying insecticides or using genetically modified mosquitoes.
Findings appear on Wednesday in the specialized journal Nature.
