Researchers have discovered and tested a new technique to engender a heritable shutdown of male mosquitoes ability to sire female offspring. This could be a much more efficient and rapid way to engineer the extinction of mosquitoes since this trait can stably achieve fixation in any population. From the abstract:
Shredding of the paternal X chromosome prevents it from being transmitted to the next generation, resulting in fully fertile mosquito strains that produce >95% male offspring. We demonstrate that distorter male mosquitoes can efficiently suppress caged wild-type mosquito populations, providing the foundation for a new class of genetic vector control strategies.
