苹楔天牛Saperda candida Fabricius（鞘翅目Coleoptera:天牛科Cerambycidae
）原产北美，主要危害果树，300多年来被认为是原产地果园最具毁灭性的害虫。2008年该
害虫首次传入欧洲（德国费马恩岛），因而受到许多国家的重视。该害虫的寄主植物苹果、
梨、李、山楂等果树在我国种植非常广泛，具有十分重要的经济价值。该天牛会随着寄主植
物的引进、调运进行远距离传播，我国应加强对该害虫的检疫。文章就其形态特征、危害特点、生物学
特性及潜在风险作一阐述。
英文摘要： The round-headed apple borer,
Saperda candida Fabricius (Coleoptera:C
erambycidae), is a native insect of North America, where it mainly attacked frui
t trees, and has been recognized as a destructive orchard pest over 300 years. I
n the summer of 2008, it has been found at the first time in Germany and in Euro
pe, and has been paid attention in many countries. Its host plants, such as appl
e, pear, plum, hawkthorn and other fruit trees, are economic important and have
been planted broadly in China. The borer is easily taken and transported over lo
ng distance with its host plants in the commerce, so quarantine of the pest must
be enhanced in China. The characters, damage, biology and risk of the roundhe
aded apple borer were introduced.
