The number of Zika cases spread by mosquito bites in Florida has risen to 25, and with the number expected to rise further, airplanes have been flying over Miami spraying naled, a neurotoxic insecticide which kills adult mosquitoes. Some scientists are warning that naled may be more dangerous than the Zika virus itself.

As health officials predicted, the Zika virus is beginning to spread across south Florida, and now a type of genetically modified (GM) mosquito designed to fight the virus has been approved by the Food and Drug Administration (FDA). [1]
