广东全民总动员开启大灭蚊

Core Viewpoint - The article discusses the outbreak of the chikungunya virus in Guangdong, China, highlighting the urgent measures taken to control the spread of the disease, including mosquito eradication efforts and innovative biological control methods [1][12]. Group 1: Mosquito Eradication Efforts - Guangdong province reported 2,940 new local cases of chikungunya from July 20 to July 26, prompting a week-long concentrated mosquito eradication campaign [1]. - Residents in Zhongshan's Huangpu Town are participating in nightly activities to burn mosquito coils, targeting peak mosquito activity times to maximize effectiveness [1][3]. - The campaign includes thorough inspections and cleaning of potential mosquito breeding sites, such as toilets, flower pots, and outdoor water accumulation areas [3]. Group 2: Innovative Control Methods - A collaborative project has developed an "electronic sentinel" that uses human scent simulators to attract and kill mosquitoes while monitoring their density in real-time [5]. - The introduction of the larger "giant mosquito," a natural predator of the Aedes mosquito, is being tested, with one giant mosquito capable of consuming 80 to 100 Aedes larvae [5][8]. - The "mosquito factory" at Sun Yat-sen University produces 4 to 5 million sterilized male mosquitoes weekly, which, when released, can significantly reduce the population of wild female mosquitoes by preventing viable offspring [8][10]. Group 3: Community Engagement and Education - Local communities are actively engaged in mosquito control, with educational songs being created to promote awareness about eliminating standing water and preventing mosquito breeding [12]. - The ongoing high temperatures and rainfall in Guangdong create favorable conditions for mosquito breeding, necessitating continued efforts in both chemical and biological control strategies [12].
