英国科学家在非洲疟疾蚊子中发现古代杀虫剂抗药性,协助新的控制努力。 British scientists found ancient insecticide resistance in African malaria mosquitoes, aiding new control efforts.

英国科学家发现了关于非洲主要疟疾传播蚊子Anopheles funestus 如何在抵制控制努力方面演变的遗传线索。 British scientists have uncovered genetic clues about how Anopheles funestus, a major malaria-transmitting mosquito in Africa, is evolving to resist control efforts. 通过分析来自656个现代和45个历史蚊子标本的基因组,研究人员发现非洲各地遗传变异很大,一些种群广泛混合,而另一些则仍然与世隔绝。 By analyzing genomes from 656 modern and 45 historic mosquito specimens, researchers found high genetic variation across Africa, with some populations mixing widely while others remain isolated. 研究表明,杀虫剂抗药性突变早在1960年代就存在,表明该物种的快速演变。 The study revealed that insecticide resistance mutations existed as early as the 1960s, indicating the species' fast evolution. 调查结果将有助于改进有针对性的控制战略,包括改造基因驱动技术,以减少女蚊子人口和遏制疟疾的传播。 Findings will help improve targeted control strategies, including adapting gene drive technology to reduce female mosquito populations and curb malaria transmission.
