Presumably, CRISPER includes improved techniques for controlling mosquitoes by targeting only the species that are vectors of importance in disease transmission. A few decades ago targeted DNA adjustments of male mosquitoes, producing only males in their offspring which would then only produce males also, was demonstrated as a way of eliminating a species in a limited study. Since only females feed on blood needed to produce viable eggs, blood feeding and disease transmission ends. The result would seem to be one of the least disruptive control mechanisms possible.
