This GOOD News for countries where the spread disease by mosquitoes is rampant.

The Aedes aegypti mosquito spreads diseases such as dengue, yellow fever, zika virus and chikungunya, making hundreds of millions of people sick in more than 120 countries each year.

A CSIRO (The Commonwealth Scientific and Industrial Research Organisation) experiment has managed to wipe out more than 80 per cent of a dengue fever-spreading mosquito near a far north Queensland town.

The CSIRO released more than three million sterile male Aedes aegypti mosquitoes in small towns near Innisfail last summer, and the females they mated with laid sterile eggs.

“We created a population of mosquitoes that had within them a naturally occurring bacterium called wolbachia,” he said.

“What we were doing is releasing only males that had this wolbachia, and they would cross with mosquitoes in the field, the wild mosquitoes that didn’t have that same strain of wolbachia, and as a result the wild females would only lay sterile eggs and so the population would crash.”

The Aedes aegypti mosquito also spreads diseases such as yellow fever, zika virus and chikungunya, making hundreds of millions of people sick in more than 120 countries each year.
