According to a new trial study, larvae eating guppy fish could possibly help fight the spread of dengue

Guppies eat larvae that grow into mosquitoes, which in turn bite humans and transmit dengue.
According to the study, the threat of exposure to dengue-carrying mosquitoes is rising with uncontrolled urbanisation and a surge in the use of non-biodegradable packaging, which can act as a water reservoir for dengue mosquito breeding.
