Southeast Asia warned of insecticide-resistant dengue mosquitoes

TOKYO — A team of researchers led by Shinji Kasai, director of the Department of Medical Entomology at Japan’s National Institute of Infectious Diseases, has warned about an increasing number of insecticide-resistant mosquitoes in Southeast Asia.

The warning comes after the team found a new genetic mutation that makes Aedes aegypti mosquitoes — also known as yellow fever or dengue mosquitoes — more resistant to common insecticides.
