标题: 每日外刊 |“杀人大黄蜂”再次现身美国,它又回来了!
背景知识

日前,美国华盛顿州农业部门证实,一种可怕的外来物种,俗称“杀人大黄蜂”的亚洲大黄蜂又出现在美国华盛顿州,当地紧急开始实施围剿方案。今年8月11日,在华盛顿州沃特科姆县布莱恩东部的一个农村地区,一名居民发现了一只存活的杀人大黄蜂。被发现时,它正在攻击普通蜜蜂的巢穴。华盛顿州农业部门计划诱捕活体大黄蜂,他们在大黄蜂可能的飞行路线沿线的树上,挂上很多以橙汁或果酱为诱饵的瓶子做陷阱。美国华盛顿州农业部门昆虫学家鲁尼表示,整个围捕大黄蜂计划主要包括三个部分,现在附近区域找到它们,这就要利用我们的陷阱和居民的报告来定位。捉到大黄蜂后,用无线电发射器给他们做标记,这样就能跟着他它们回到巢穴。它们的巢穴通常隐藏在森林身处的浓密灌木丛中,最终目标就是根除它们的蜂巢。“杀人大黄蜂”的体型接近5厘米,能以每小时32公里的速度飞行,它们可以在几个小时内杀死整个蜂巢的蜜蜂,有时也会对人类发起攻击,其毒性和一些毒蛇的毒液相当。美国疾控中心的数据显示,大黄蜂、黄蜂和蜜蜂平均每年造成62人死亡。

First murder hornet nest of 2021 found in Washington state

华盛顿州发现2021年第一个“杀人大黄蜂”的巢穴

The first Asian giant hornet nest of 2021 has been found in Washington state, roughly a week after a live hornet was spotted in the state for the first time this year. The nest was discovered in a rural area east of Blaine, Washington, on Thursday, about a quarter-mile from where a resident spotted a live hornet on 11 August. According to the Washington state department of agriculture, experts were able to locate the nest after putting trackers on three hornets in hopes of finding their nest.

华盛顿州发现了2021年的第一个亚洲大马蜂窝,大约一周前,今年首次该州发现了一只活的大黄蜂。这个蜂巢于上周四在华盛顿州布莱恩市以东的一个农村地区被发现,距离当地居民8月11日发现活大黄蜂的地点约四分之一英里。据华盛顿州农业部称,专家们在三只大黄蜂身上安装了追踪器,希望能找到它们的巢穴。

One hornet slipped out of the tracking device, another hornet was never located and one eventually led the team to their home. WSDA experts narrowed the search area by 17 August but were unable to access the location until Thursday. A WSDA tracking team, along with the Oregon department of agriculture and USDA’s animal plant health inspection service then began searching the area at 7:30am and eventually spotted the nest at 9:15am, local time.

一只大黄蜂从追踪装置中溜了出来,另一只大黄蜂从未被定位,最后一只大黄蜂将(搜索)团队带到了它们的巢穴。WSDA专家在8月17日之前缩小了搜索范围,但直到周四才进入搜索位置。WSDA的一个跟踪小组,连同俄勒冈州农业部和美国农业部的动物植物卫生检查部门,在早上7:30开始搜索该区域,最终在当地时间上午9:15发现了这个蜂巢。

Asian giant hornets are also known as “murder hornets”, primarily because they prey on other, smaller insects. Native to Asia, the hornets pose a threat to honeybees and native hornet species. If left to spread unchecked, the hornets can destroy a honeybee hive in just hours by feeding on the larvae and decapitating bees in what scientists call their “slaughter phase”, feeding severed body parts to their own young.

亚洲大黄蜂也被称为“杀人大黄蜂”,主要是因为它们捕食其他较小的昆虫。大黄蜂原产于亚洲,对蜜蜂和本地大黄蜂构成威胁。如果任由大黄蜂肆意蔓延,它们可以在短短几小时内摧毁一个蜂巢,以幼虫为食,将蜜蜂斩首,并把切断的身体部位喂给自己的后代,科学家称之为“屠宰阶段”。
