The technique of using X-rays to sterilise the male mosquitoes and then releasing them into the wild is a new way to try and control the mosquito population, which has increased sharply in recent years due to warming temperatures and increasing immunity to pesticides.
The DOH asks for support in reducing the potential for the spread of Zika virus, which is carried by mosquitoes. Vector control teams are responding and will continue operations in areas where the individuals spent time, including neighborhoods in Waialua/Haleʻiwa area on Oʻahu.
