A plague of hornets, each the size of a human thumb, have descended on Shaanxi province this summer—at least 28 have been stung to death (link in Chinese), while another 419 have been injured, according to a local news report from China Radio Network (CRN), via the New York Times’ Chris Buckley. The death toll from hornet attacks in Ankang city is more than twice the annual average between 2002 and 2005, say the Ankang police, as the Guardian reports. A local doctor said hospitalizations due to hornet attacks have risen steadily over the years (link in Chinese).

Why the uptick? The population of Asian giant hornets (vespa mandarinia), as they’re known, has surged largely because of climate change, says the Shaanxi Provincial Forestry Department (link in Chinese). The average winter temperature in Ankang rose 1.10 ℃ in the span of a few years alone, allowing more hornets to survive the winter. And it’s not just China; rising temperatures are behind the spread of another deadly Chinese hornets species, vespa velutina, in South Korea and Europe.

The chief prey of the Chinese hornet? Honeybees. As global warming makes more of the world hospitable to Chinese hornets, more honeybees are dying in the beepocalypse. Areas in Europe where they’re likeliest to invade “hold among the highest densities of bee-hives in Europe,” according to recent research. Here’s a heat map of where Chinese hornets will be able to survive as temperatures rise.

​”Climate change increases the risk of invasion by the Yellow-legged hornet,” Barbet-Massin, et al.

Japanese honey bees have figured out how to fight back, by cooking hornets. After surrounding a hornet in a spherical formation, Japanese honey bees engage their flight muscles, raising their collective temperature beyond what hornets can withstand.

European honey bees lack this skill. That’s why bee populations in France, where Chinese hornets arrived via a Chinese pottery shipment in 2005, have already taken a hit. Since then, Chinese hornets have spread at a pace of up to 100 km (62 miles) a year. Within the last three years, they’ve invaded Spain, Portugal and Belgium; soon they’ll arrive in Italy and the UK, says the European Environment Agency.

But the havoc climate change is wreaking on rural China are more immediate. Being stung feels “like a hot nail through my leg,” as one entomologist put it, and their venom can dissolve skin. They’re fast, too, flying up to 25 miles per hour (41 kilometers an hour). They’re also the largest hornets on the planet, reaching 5.5 centimeters (2.2 inches). Via hornet blogger Kurt Bell, here a look:

Here’s a chilling scene that Chen Changlin, an Ankang farmer, witnessed one evening a few days ago. As he harvested rice on evening, hornets swarmed a woman and child working nearby. When they reached Chen, they stung him for three minutes straight. Chen made it; the other two died. “The more you run, the more they want to chase you,” said another victim, whose kidneys were ravaged by the venom. When he was admitted to the hospital, his urine was the color of soy sauce.

That species hasn’t spread outside of Asia yet, though sightings in the US of giant Asian hornets have been cropping up of late. If the Asian hornet spreads in the US, it could be an even bigger threat than the Chinese hornet.

They too thrive on killing honey bees. Not only are they five times bigger, but their huge jaws allow them to decapitate bees so quickly that one giant hornet can kill 40 bees a minute. A swarm of fewer than 30 can wipe out a 30,000-strong honeybee colony in just a few hours.

原标题:陕南蜂狂

近一段时间,毒蜂蜇人夺命事件在安康、汉中、商洛等地频频发生。

据安康3家大医院统计,3个月内已有230余人被蜇伤,21人不幸殒命;今年以来,汉中3家医院收治蜂蜇病人109例,其中6人死亡;商洛市中心医 院近期也接诊8起,其中1人死亡。被蜇者多集中在农村及偏远山区。胡蜂(又称马蜂、黄蜂),体大身长毒性也大,人被蜇后会出现过敏反应和毒性反应,严重者 甚至导致死亡,其蜂巢被老百姓称为“葫芦包”。

案例

黄蜂追了200米蜇人

9月24日,躺在安康市中心医院肾病科病床上的陈昌林说,21日下午5时,他帮亲属打稻谷时,见一对母子被黄蜂包围准备去救助,结果那些成人大拇指长的蜂在他的头、腰、腿猛蜇,“我跑向路边呼救,可黄蜂一直追了200米,围着我蜇了将近3分钟……”

值班医生称,目前诊断陈昌林为急性肾衰竭,处于无尿状态,只能依靠血液透析。“已经花了近万元,也不清楚还要花多少钱。”陈昌林的儿子陈忠春说。

陈忠春还说,听人说被黄蜂包围的那对母子抢救无效不幸身亡。

5旬农妇稻田边被蜇200针

安康市汉滨区流水镇三坪村村民穆从会,今年55岁,在安康市中心医院已经住了近一个月,但目前仍小便失禁。

穆从会称,8月27日下午5时许,她刚走到稻田边的山地,“山边突然冒出一堆胡蜂,我穿着长袖长裤,还是被蜇得腿上、头上、胳膊上到处是伤疤,医生说有200多个。”

马蜂受惊扰蜇伤六旬老汉

9月24日下午,镇巴县赤南镇刮大风,路边椿树枝头的马蜂窝被刮得左右摇摆,马蜂受到惊扰,绕着树干盘旋而下,黑压压一片。68岁的老钟背着一背篓玉米刚好走到树下,惨剧发生了。

9月25日下午,在汉中市3201医院急症科,病床上的老钟痛苦地说,发现马蜂时,已经来不及躲避,“我把背篓放下,拿背垫不停地打,赶不走啊!”老钟头部、双侧臀部、股部等多处被马蜂蜇伤。

5133-hornet-2一斗土倒下去马蜂围上来

镇巴县巴庙镇48岁的覃先生在汉中市中心医院肾病内科治疗。9月17日上午11时,覃先生开挖掘机倒土时,把一斗土倒进路沿下树丛中的马蜂窝,马蜂 哄起飞进挖掘机驾驶室内,将他团团围住。覃先生跳下挖掘机,边跑边拿着脱下的短袖甩打胡蜂群,跑了大约40米,他躲进一农户家里,蜂群才渐渐散去,这时他 身上已经被蜇了40多下。他说,村民后来去看,那个马蜂窝有煤气罐那么大。

症状

症状不一均有脏器损伤

安康市中心医院肾病内科主任医师米琳介绍,胡蜂在陕南山区较为常见,每年秋季常有被胡蜂蜇伤的患者来就诊。被胡蜂蜇伤后,通常会胸闷、心慌并患上中毒性肝炎,严重的会引发肾脏、肝脏、心脏的损害,患上急性肾功能衰竭等病症。

安康市中医院肾脏科副主任陈卫红介绍,胡蜂伤人事件住院患者每年均有所增加。患者临床症状不一:有一年患者出现类似于重症胰腺炎表现,病人腹痛,淀粉酶增高;但有一年患者出现重度溶血反应,表现在肾功能衰竭;还有一年,患者出现急性呼吸紧迫综合征等。

被胡蜂蜇10针就应到医院

汉中市中心医院肾病内科主任王敬表示,“被蜇伤口10处以内算轻伤,医院会采取促进排尿等措施治疗,四五十处被蜇伤就需赶紧送进有透析条件的医院,因为蜂毒会进入人体,破坏红细胞,重者会引起肝肾功能衰竭,导致死亡。”王敬表示,因为胡蜂种类繁多,目前并无治疗的特效药。

安康市疾控中心相关负责人认为,被胡蜂蜇10针左右就应立即到大型医院就诊,被蜇30针以上应立即采取紧急措施抢救。

措施

每年秋季都成立救治小组

安康市中心医院一位负责人介绍,针对安康多发胡蜂伤人事件,每年秋季该院都会成立蜂蜇救治小组,以便患者能得到及时有效的治疗。目前,该院正向有关 单位申报陕西省秦巴山区胡蜂蜇伤救治的科研项目,专门针对蜂蜇进行研究的医学项目。但他认为,防治胡蜂,公众首先是做好相关应急预防。

拟适当提高医疗报销比例

昨日,安康市卫生局一名负责人介绍,该局也注意到近日被蜂蜇的人数有所增加的情况,也了解到被蜇者多集中在农村及偏远山区。

该负责人表示,就这部分患者的报销问题,该局拟在做全面统计后,对于被蜂蜇伤的患者,适当提高医疗报销比例。

3个月摘除300余“葫芦包”

记者从安康市消防支队获悉,今年7月至今,已累计摘除300余个“葫芦包”。这些“葫芦包”多分布在城乡结合部的居民楼和人流量较大的生活区。消防 部门提醒,如遇“葫芦包”成型,应及时拨打119求助。 预防葫芦包主要在于加强思想重视,躲在作业的田间地头观察,如果发现有胡蜂活动,尽量找专业人士或者对除掉葫芦包有经验的人来做处理

在胡蜂活动中心区域被蜂蜇伤,应快速脱离,随后,在地势开阔的安全地带蹲在原地。如果误惹了蜂群,要用衣物保护好头颈,反向逃跑或原地趴下。千万不要试图反击,否则只会招致更多的攻击

农民在收割玉米,稻谷时应在确定无胡蜂安家筑巢前提下,尽量将农作物收拾干净,避免胡蜂筑巢形成葫芦包伤人

野外被蜂蜇咋处理伤口

若被蜜蜂蜇伤,在力所能及的情况下将蜂刺挑下,如是蜜蜂所蜇用肥皂水等涂抹,如是被胡蜂所蜇应用食醋清理伤口

被胡蜂蜇后切忌用手挤压,并及时到就近的医疗机构使用抗过敏药和激素

在条件允许的情况下,应在大量喝水时观察尿液和尿量,如全天6小时内尿液量少于0.5ml/kg/每小时,应及时就医或拨打120求助

■给你提醒

进山应穿厚实完整的紧口衣服

目前正值胡蜂活动高发期,安康市中医院肾病科副主任陈卫红提醒,进山应穿着厚实完整的紧口衣服,戴上帽子,切勿露出胳膊、小腿等部位,不要穿颜色鲜艳的衣服,不要涂抹化妆品和香水,若遇蜂巢应绕行避开,不要靠近。

安康市疾控中心相关负责人提醒,家长应教育并看管好孩子,不要主动攻击胡蜂,同时也可请专业人士消除胡蜂滋生场所。(来源:华商网-华商报)
