In 2009, researchers acquired a laboratory colony of Aedes aegypti in Delhi and kept it without insecticide pressure. 17 years later, 10 micrograms killed 97.91% of females, yet survivors rapidly activated detoxification enzymes

A Delhi study reveals mosquitoes surviving common insecticide treatments. This survival gap suggests a potential early warning of developing resistance. Researchers identified specific enzymes aiding the mosquitoes' detoxification processes. This finding necessitates careful monitoring and adaptation of control strategies. Public health teams must track enzyme activity and field mortality to adapt.
