  炎炎夏日,最恼人的莫过于蚊子。今日一则喜大普奔的音讯是,我国科学家总算找到了消除一大种群蚊子的办法。

  据CNN报导,在我国广东省的两个岛屿上进行的一项实验,简直彻底消除了世界上侵略程度最高的一个蚊子种群。

  该实验成功地将雌性亚洲虎蚊的数量减少了94%,使人类被吸食的次数减少了97%。雌虎蚊是蚊虫吸食和疾病传达的首要来历。

  蚊子生态学家Peter Armbruster在一份声明中说,考虑到蚊子坚强的生存才能,这项实验是迄今为止最成功的灭蚊实验之一。

  Experts said the Asian tiger mosquitoes are particularly hard to eradicate using conventional population control methods, such as pesticides and removing stagnant water where the insects lay their eggs.专家表明,运用传统的种群操控办法,如杀虫剂和铲除蚊子产卵的积水,特别难以根除亚洲虎蚊。The white-striped mosquitoes have been described as highly invasive and have spread from Asia to almost every continent over the past 40 years, according to the studys authors.该研讨报告的作者称,这种带有白色条纹的蚊子具有“高度侵略”才能,在曩昔40年里,它们现已从亚洲传达到简直各个洲。Mosquitoes pose grave threats to human health beyond just irritating bites. The World Health Organization (WHO) has described the insects as one of the deadliest animals in the world, due to their ability to rapidly spread deadly diseases such as dengue fever and malaria.蚊子对人类健康的严重威胁不仅仅仅仅令人讨厌的吸食。世界卫生组织称这种昆虫是“世界上最丧命的动物之一”,由于它们能够敏捷传达登革热和疟疾等丧命疾病。

  广州是一个人口密布的热带城市,2014年广州迸发登革热疫情期间,该市约有37350人感染登革热。本月,菲律宾卫生部门发布了“全国登革热警报”,在2019年上半年就有450多人死于登革热。

  此外,奚志勇教授还告知《新闻周刊》,这种灭蚊办法对环境友好,有或许被广泛用于操控带着疾病的蚊子。He explained the SIT technique had already been used to successfully suppress and predicate a number of agricultural insect pests, such as medfly and tsetse flies. But despite a huge effort, it had never before been successfully used in tackling mosquitoes.他解说说,昆虫绝育技能现已成功地用于按捺和供认一些农业害虫,如地中海实蝇和采采蝇。可是,虽然付出了巨大的尽力,它此前从未成功地用于抵挡蚊子。The findings are promising, but Xi acknowledged: In terms of disease control, this approach may not be suitable in emergency situations during disease outbreak.研讨结果很有期望,但奚志勇供认:“在疾病操控方面,这种办法或许不适用于疾病爆发期间的紧急情况。”This research can be extended to control malaria and other mosquito-borne diseases, and for agricultural pest control as well, he said. The technique could be used to create areas protected for humans, as well as food and plants.“这项研讨能够扩展到操控疟疾和其他蚊媒疾病,以及农业害虫操控,”他说。这项技能能够用来为人类、食物和植物发明保护区。It can also be used to prevent the global expansion and invasion by highly invasive insect species to restore the ecosystem. This green technology is especially useful and cost-effective for those island countries in tropical regions to generate mosquito vector-free environment, Xi concluded.“它还能够用来避免高度侵略的昆虫物种在全球范围内的扩张和侵略,然后康复生态系统。”这一绿色技能关于热带地区的岛国发明‘无蚊媒’环境特别有用和合算,”奚志勇总结道。
