Since older mosquitoes are more likely to harbour diseases that can be passed to people, Australian researchers say they may have found a way to stem the process: make the mosquitoes die younger.
Parasite cuts mosquito lifespan
So scientists at the University of Queensland tried introducing mosquitoes to a bacterial parasite that cut the insects' lifespan by about half, to an average of 21 days from 50 days, the wire service reported.
Science, lead researcher Scott O'Neill said the discovery could prove to be a safer alternative to the widespread use of insecticides.
