Mosquitoes rapidly evolving enzyme defenses against common insecticide

In a Delhi laboratory, researchers have glimpsed the early architecture of a future crisis: Aedes aegypti mosquitoes, the carriers of dengue and Zika, are beginning to marshal their own biochemical defenses against α-cypermethrin, one of humanity's most relied-upon insecticides. Though the insects still die in great numbers, the molecular signatures of resistance are already present — a reminder that evolution does not wait for permission, and that the tools we build against nature are always, in time, being unmade. The findings from Dr. Rohit Lakhwani and colleagues at the University of Delhi
