在新加坡，蚊子正在消灭蚊子

Core Viewpoint - Singapore is implementing a mosquito breeding program to combat the spread of dengue fever and other mosquito-borne diseases by releasing genetically modified male Aedes aegypti mosquitoes that carry the Wolbachia bacteria, which reduces the mosquito population and virus transmission [1][2][10]. Group 1: Mosquito Breeding Program - The program is operated by the National Environment Agency of Singapore, producing approximately 5 million male Aedes aegypti mosquitoes weekly [1][10]. - The breeding facility, referred to as a "mosquito apartment," maintains strict environmental controls, including a temperature of 28 degrees Celsius and humidity of 80% [1][7]. - The project aims to cover 800,000 households by 2026, which is half of all households in Singapore [10]. Group 2: Wolbachia Bacteria - The male mosquitoes are implanted with Wolbachia bacteria, which do not harm humans but prevent the offspring from hatching when they mate with uninfected females [2][3]. - This mechanism, known as "cytoplasmic incompatibility," is designed to reduce the overall mosquito population and limit the spread of diseases [3]. Group 3: Mosquito Lifecycle Management - The breeding process involves careful monitoring and feeding of mosquito larvae, with each layer of the breeding trays housing exactly 26,000 larvae to ensure uniform growth [7][8]. - Advanced technology, including AI and automated feeding systems, is utilized to enhance efficiency and standardization in the breeding process [7][8]. Group 4: Public Perception and Impact - Initial public concerns about increased mosquito presence have been addressed by studies indicating that the perceived increase in bites may be due to heightened awareness rather than an actual rise in mosquito numbers [9]. - Research shows that in areas where the modified mosquitoes are released, the risk of dengue fever infection has decreased by approximately 75%, and the population of Aedes aegypti mosquitoes has reduced by 80% to 90% [10].
