在入境集装箱中截获的一种美洲产次生蛆症蝇类——次生锥蝇（双翅目：丽蝇科）

American Secondary Screwworm Fly Cochliomyia macellaria （Fabricius, 1775） Intercepted from Entry Cargoes in Port, China （Diptera： Calliphoridae）

次生锥蝇Cochliomyia，macellaria（Fabricius，t775）为美洲特别是热带区常见次生蛆症蝇类，对农业、畜牧业及人民生活均有重要影响，尤其对畜牧业危害巨大。2006—2008年中国出入境检验检疫局分别从来自墨西哥、秘鲁、美国和巴拿马的集装箱货物中截获次生锥蝇4♂♂、38♀♀，由于中国境内无该种分布，且相关中文资料甚少，因此，本文据截获标本对该种分类特征进行重描述并对其经济重要性等作了探讨。

Cochliomyia macellaria （Fabrieius, 1775） 4 ♂♂ , 38 ♀♀were intercepted during 2006 - 2009 from cargoes entered to China from Mexico, Peru and Panama. As a common secondary screwworm fly in America, the species is of considerable economic importance to both human and livestock for its abundance and distributions in Neotropie Region and southern part of Nearctie Region. There is no record in Chinese mainland up to date. The present paper deals with a redescription of the species both sexes and a discussion for its economic importance.
