冰岛报告随着气候变暖,蚊子出现。
Iceland reports the presence of mosquitoes as climate warms

冰岛本周通过自然科学研究所的确认,正式记录了首次蚊子发现——三只*Culiseta annulata*。此前,冰岛被认为是地球上(连同南极洲)仅有的两个没有蚊子的地区之一。 这些蚊子可能通过货运抵达,并且能够适应冰岛的气候,这一因素日益受到全球变暖和国际运输增加的影响。昆虫爱好者比约恩·赫雅尔塔松在雷克雅维克附近发现了这个物种,它在欧洲和其他北欧国家很常见,以叮咬人造成骚扰而闻名,而非传播疾病。 这一发现凸显了气候变化的影响,因为气温升高使物种能够扩大其分布范围。虽然这些蚊子在该地区不携带已知感染,但它们的出现标志着冰岛生态系统的转变。

## 冰岛与蚊子:黑客新闻讨论摘要 近期关于冰岛出现蚊子的报告(该国此前无蚊)引发了黑客新闻的讨论。虽然 NPR 将蚊子的出现与气候变化联系起来,但许多评论员对此观点提出了质疑。一些人指出,蚊子在其他寒冷地区也能茁壮成长(格陵兰、西伯利亚、加拿大),并且*Culiseta annulata* 这一物种适应寒冷气候。 讨论的重点在于,是气温升高促使蚊子定居,还是蚊子通过贸易/旅行抵达,现在由于其他因素(可能包括降水变化或微妙气候平衡被破坏)而得以生存。一些人指出,冰岛最近昆虫生物多样性有所增加,可能与气候变暖有关。 其他讨论点包括蚊子可能通过船只抵达、蚊虫叮咬反应的传闻证据,以及冰岛历史上无蚊的记录。对话还涉及疾病传播的可能性(尽管冰岛蚊子已知不携带疾病)以及蚊虫叮咬带来的普遍不适。

Icelanders may be the last group of people on Earth to experience the pesky bite of a mosquito.

This week, Iceland recorded the presence of the insects within its borders for the first time in the Nordic nation's history.

The discovery of three Culiseta annulata mosquitoes was confirmed Monday by the Natural Science Institute of Iceland, which said the mosquitoes likely arrived by freight and appeared to be able to withstand Iceland's climate. (There have been previous reports of mosquitoes found in airplanes in Iceland.)

The institute noted that the mosquitoes were one of a number of new insect species discovered in Iceland in recent years due to a warming climate and the growth of international transportation.

Insect enthusiast Björn Hjaltason said he found the mosquitoes on a farm in Kjós, just north of Reykjavík, earlier this month.

"At dusk on the evening of October 16th, I caught sight of a strange fly on a red wine ribbon," Hjaltason told Icelandic broadcaster RUV. "I immediately suspected what was going on and quickly collected the fly. It was a female."

Hjaltason later trapped two more. All three insects were turned over to authorities for testing, which revealed that they were two female and one male mosquitoes.

Antarctica is now the only place in the world believed to have no mosquitoes.

Climate change is causing temperatures to rise across the world, and the Arctic region is warming at more than double the rate of the global average.

According to the Natural Science Institute of Iceland, the species Culiseta annulata are large mosquitoes present in Europe and other Nordic countries that can live in cold weather, usually finding shelter in outbuildings and basements.

Though they sting, the institute said they don't carry known infections in those areas. One study from 2017 said Culiseta annulata are often "regarded as a biting nuisance, rather than a deadly foe."

There are more than 3,000 species of mosquitoes around the world, some of which can transmit severe and even fatal diseases through their bites such as malaria, dengue fever and West Nile virus.
