One involves engineering reproductive isolation (speciation) between populations that can otherwise interbreed, so as to limit gene flow; a second involves creating genetic methods that can, reversibly, drive populations of invasive species and / or vectors of disease to local extinction; a third involves creating genetic methods that can drive — in ways that are easily reversible — the spread of beneficial genes into wild insect populations so as to prevent the spread of vector - borne disease.
