The meat of the story is that researchers report initial success from the first test release into the wild of these mutant bugs. Their job....to pass on a lethal gene to their offspring that kills them before reaching maturity.
Of course the end result is not just eradication of pest blood suckers but the control of agricultural pests and disease bearing insects that carry illnesses like Malaria or Dengue Fever.
And of course they are up against public fears over mutations. As XNewsMan says...I hate giant Skeeters! Haven't These guys ever read any science fiction?!!!! lol
