Genetically engineered organisms are generally less able to survive in the wild then their non-genetically engineered cousins. Luminescent moths may be more susceptible to predation then dully colored moths, and sterile moths will certainly have difficulty in passing down their genes to the next generation. Genetically engineered traits are the result of arbitrary human choice, whereas natural traits are chosen by natural selection, and so are much more likely to be beneficial.
