- Mars008 1y agoThere was a 'barrier' somewhere between Mexico and South America where sterile male flies were regularly released. They outnumbered natives and stopped reproduction cycle. Till recently. Now without control flies spread north into their historical territory. With warming climate they can spread even further. Wiki has a bit of info on it: https://en.wikipedia.org/wiki/Cochliomyia_hominivorax https://en.wikipedia.org/wiki/Cochliomyia_hominivorax
