广州：释放“绝育雄蚊” 阻击基孔肯雅热

Core Viewpoint - The article highlights the innovative "mosquito factory" in Guangzhou, which produces sterilized male mosquitoes to combat the spread of the chikungunya virus through biological control methods, representing a significant advancement in pest management technology [1][4]. Group 1: Technology and Methodology - The "mosquito factory" produces 5 million sterilized male mosquitoes weekly, utilizing a biological technique to disrupt the breeding cycle of the Aedes albopictus mosquito, which is responsible for transmitting chikungunya and dengue fever [1][4]. - The technology involves breeding male mosquitoes that carry the Wolbachia bacteria, which, when mated with wild female mosquitoes, results in non-viable eggs, effectively reducing the mosquito population over time [2][3]. - The precision of the method is notable, with an error rate of less than 0.5% in sorting mosquito larvae and less than 0.3% in the emergence of male mosquitoes, ensuring high efficiency in the breeding process [2]. Group 2: Effectiveness and Results - The "mosquito control" strategy has shown significant results, with a reported 90% control rate of Aedes albopictus in trial areas, and no dengue fever cases reported in the last seven years in the tested regions [3]. - The method can reduce mosquito populations by 50% within three weeks and achieve an 80% reduction in wild mosquito density within 6 to 8 weeks of implementation [3]. - The company plans to continue its efforts in mosquito control and collaborate with local organizations to maintain ongoing pest management strategies [4].
