Mysore man fights deadly dengue with guppy army – The Times of IndiaPosted: May 30, 2013
The guppy, a freshwater species, feeds on the larvae of mosquitoes that spread diseases like malaria and dengue.
Putting this knowledge to good public use is Mysore-based entrepreneur Somashekar Gowda, who’s taken the initiative to distribute guppies free in the villages of Mysore district to stop the spread of mosquito-related diseases. People from other districts, including Bangalore, are visiting Gowda’s house to collect bowlfuls of guppies. Using fish to control malaria used to be a standard approach in India, but when insecticides like DDT were introduced, this biological weapon was ignored. Now, mosquitoes have become resistant to many of these chemicals and fish are back in the spotlight.
