Killer mosquito changes breeding grounds – The Times of IndiaPosted: August 22, 2012
A recent study by the Kolkata Municipal Corporation’s (KMC) entomology department has revealed that the deadly mosquito — associated with both dengue and yellow fever — has changed its life-cycle in a major way, leading to severe concern among experts trying to combat the disease. While some believe this has happened due to mutation in the insects’ genes, experts like Amiya Kumar Hati, former director of the School of Tropical Medicine in Kolkata, say that it has simply changed its behaviour to match the environment.
“Till recently, we knew that the Aedes Aegypti bred in stagnant water tanks inside bathrooms, under refrigerators (where water collects after decompression) or in small pots in the house where sunlight doesn’t reach. But the recent study has revealed that this variety of mosquito is now breeding in open spaces along with the malaria-causing Anopheles. This may have happened due to rapid urbanization and changes in the environment,” said Debasis Biswas, chief entomologist, KMC.
