There it waits to be delivered to the next victim when the insect feeds again. The idea is to interrupt the relationship between the insect and its pathogens that use it for transport. Once these "good" mosquitoes are created, scientists are hoping to be able to release them into the world where they can breed and interbreed with other species and do away with this enemy insect that has killed thousands. But as genetic research is about to step forward, there are many doubts about releasing genetically engineered life forms into the environment. It is quite possible that the miracle, ...
