南京地区近日出现大量蚜虫,随风四处飘飞沾落在各处。其他地方包括北京也出现蚜虫恐慌。北京卫生部门告知,北京的气候条件不适合蚜虫生存。
据香港媒体报道,南京发现空气中的柳絮一样的漂浮物落在身上竟然会动,而且还会留下一些类似水渍的痕迹。根据南京市园林科研所专家说,南京空中飘浮的白色絮状物主要是榆四脉绵蚜,是一种蚜虫,因形似柳絮,被误认为是柳絮。专家认为,南京产生大量蚜虫的原因是当地的气温和湿度较高有助于其生长。
南京的蚜虫也引起全国许多城市市民的担忧,人们纷纷开始怀疑自己所在地的飞絮也是这种榆四脉绵蚜。
不过郑州、南阳等地媒体纷纷辟谣。近日,北京市民也开始怀疑榆四脉绵蚜的存在,网友在网上纷纷表示:北京是不是也有这种榆四脉绵蚜,怪不得最近过敏的人变多了。
中国林业科学研究院林业研究所专家出面辟谣,指出蚜虫生存需要的温度和湿度较高,早春的北京并不具备相应的环境。
但专家承认,如果说有小飞虫附着在柳絮上,这是有可能的,但不是蚜虫,北京地区不可能出现这种现象。\
