Mating sterile male mosquitoes with wild female mosquitoes can prevent mosquito eggs from hatching or larvae from developing, which can control mosquito populations. The technique of insect sterility was developed by two entomologists in the 1950s. Firstly, pest larvae were treated with radioactive radiation to select sterile male insects. Then, a large number of treated male insects were released and mated with wild female insects, preventing them from producing offspring normally and achieving the goal of controlling pest populations.   Researchers successfully eliminated the green headed flies on the island by releasing male flies that were sterilized by irradiation. Another field release experiment was conducted on a 460 square kilometer island, achieving fly purification in just 7 weeks. Afterwards, this technology was widely adopted in many countries and regions around the world, successfully eliminating green headed flies.
