I thought we did similar modifications to the screw-worm fly https://en.wikipedia.org/wiki/Cochliomyia_hominivorax https://en.wikipedia.org/wiki/Cochliomyia_hominivorax If I remember the procedure better, they radiated thousands of pounds of males so hey were sterile. They evidently only mate once, so it destroyed the population. I don't remember any real dissent discussion. The negatives of getting rid of them were minor compared to the pain and suffering this parasite introduced. They are much more of what we think of as "tropical disease/parasite". I'd warn anyone looking at more detailed pictures other than wikipedia I linked.
