秦皇岛港入境船舶截获输入性活蠓及贝蠓属一新种(双翅目:蠓科)

Notes on the introduced living midges and a new species of genus Bezzia(Diptera:Ceratopogonidae) collected on entry ships arrived at Qinhuangdao port

目的调查了解入境国际航行船舶携带输入性蠓类的情况。方法在秦皇岛港检疫锚地停泊的入境船舶生活区内采集输入性活蠓并进行分类鉴定。结果 2014年4-6月在5艘入境船舶上捕获33只输入性活蠓,经分类鉴定隶属于蠓科的蠓科库蠓属Culicoides和贝蠓属Bezzia及其他属部分种类。其中在来自朝鲜大安港(DAE AN)的塞拉利昂籍"龙岗7号"入境船舶上采获一只雄性贝蠓经鉴定为新种,遂以该船舶名称命名为龙岗贝蠓(Bezzia longgangi Yu,Nie et Yang sp.nov.),这是我国第三次报道在入境船舶上捕获输入性贝蠓新种。所携带的部分库蠓分别为环斑库蠓(C.circumscriptus Kieffer,1918)、荒川库蠓(C.arakawae Arakawa,1910)和尖喙库蠓(C.oxystoma Kieffer,1910)。结论此次发现再次提示我们应高度重视国外蠓类等外来生物的入侵。

It is the third report that the new species of Bezzia were collected on entry ships in China. Other Culicoides species were C. circumscriptus Kieffer, 1918, C. arakawae Arakawa, 1910 and C. oxystoma Kieffer, 1910. Conclusion This report is calling for high attention on the invading of foreign species of midges to our country again.
