科学家开发“毒男性”蚊子,以减少疾病传播和减少杀虫剂使用。 Scientists develop "toxic male" mosquitoes to reduce disease spread and lower pesticide use.

澳大利亚麦克夸里大学的科学家开发了一种名为“毒男性技术”的新方法,以控制蚊子人口并减少登革热和Zika等疾病的传播。 Scientists at Macquarie University in Australia have developed a new method called the "toxic male technique" to control mosquito populations and reduce the spread of diseases like dengue fever and Zika. 这一技术涉及基因改变的雄蚊子,以生产毒液蛋白,一旦在交配期间转移给雌蚊子,就会降低其寿命和传播疾病的能力。 This technique involves genetically modifying male mosquitoes to produce venom proteins that, when transferred to females during mating, reduce their lifespan and ability to spread disease. 该方法旨在将供血率降低40%至60%,并提供替代农药的替代品,并计划进一步进行安全测试。 The approach aims to reduce blood-feeding rates by 40-60% and offers an alternative to pesticides, with further safety tests planned.
