A recent study by experts from the Tata Institute for Genetics and Society (TIGS) has disturbed the sleep of Bengalureans, quite literally.
The research confirms what many have suspected for a while — the city's mosquito population is getting smarter.The TIGS study revealed two concerning developments.First, the mosquitoes have developed certain enzymes that detoxify the insecticides inside their bodies.
This helps the larvae or adults survive by neutralising the insecticides, rendering them ineffective.
This is a classic case of evolution at play.The second cause for concern is the mosquitoes' newfound ability to adapt to human behaviour.
Exploring alternative mosquito control methods, such as introducing larvicidal fishes or adopting biological repellents derived from natural products, might be necessary.The key takeaway here is that we need a multi-pronged approach, say experts in the wake of the ever-increasing number of dengue cases in the city.Exploring alternative methods of control, promoting public awareness about smarter mosquitoes, and investing in research to develop new methods that can stay ahead of the mosquito's evolutionary curve seems to be the only way forward.

This is a classic case of evolution at play.The second cause for concern is the mosquitoes' newfound ability to adapt to human behaviour. The study suggests that mosquitoes can now detect repellents and closed curtains, allowing them to target exposed areas or enter homes during low-light hours.For example, if repellents are turned on in a particular house, mosquitoes wait until 8-9 hours later when it is switched off before entering, said experts from TIGS.This enhanced awareness poses a significant threat, as it renders traditional preventative measures like mosquito nets and insect repellents less effective.Public health experts are urging citizens not to panic but to adapt their strategies.
