What could possibly go wrong?
– Concerns Are Raised About Genetically Engineered Mosquitoes (New York Times, Oct. 30, 2011):
These mosquitoes are genetically engineered to kill — their own children.
Researchers on Sunday reported initial signs of success from the first release into the environment of mosquitoes engineered to pass a lethal gene to their offspring, killing them before they reach adulthood.
The results, and other work elsewhere, could herald an age in which genetically modified insects will be used to help control agricultural pests and insect-borne diseases like dengue fever and malaria.
But the research is arousing concern about possible unintended effects on public health and the environment, because once genetically modified insects are released, they cannot be recalled.
