Delhi Study Finds Aedes Aegypti Mosquitoes Showing Resistance to Key Insecticide

A new study by University of Delhi researchers has found that Aedes aegypti mosquitoes may be developing reduced susceptibility to alpha-cypermethrin, a widely used insecticide. Laboratory tests revealed a measurable decline in the chemical's effectiveness against the mosquito species. Scientists identified specific enzymes in the mosquitoes that appear to help break down the insecticide, contributing to the resistance. The findings raise concerns about the long-term viability of relying on a single insecticide for mosquito control. Researchers are calling for more diverse and integrated pest management strategies to address the growing resistance.
