Google wants to release 16 million sterile mozzies. Our Australian tests offer a valuable lesson

Google's Debug initiative is seeking permission from US regulators to release thirty-two million sterilized male mosquitoes in California and Florida over two years. The males carry a bacterium called Wolbachia that makes them unable to produce viable offspring when they mate with disease-carrying females—essentially using the mosquitoes against themselves to suppress populations. The approach was already tested in Australia, where researchers released three million Wolbachia-carrying males in north Queensland towns starting in twenty eighteen, achieving ninety-five percent population suppression in one location, per The Conversation Australia. The trial's success suggests the strategy can work at scale, though long-term benefits depend on local ecology and community participation.
