云杉芽虫Choristoneura fumiferana（Clemens），（鳞翅目：卷蛾科（Tortricidae）最早是从弗吉尼亚采集的标本中描述的，17但这种本地昆虫主要出现在从纽芬兰以西到麦肯齐河（McKenzie River）的北方北方森林中，靠近北纬66°。53最广泛和最具破坏性的爆发发生在沿海省份（新玩法、新斯科舍省、纽芬兰）、魁北克、安大略、缅因州和五大湖州。这种食叶昆虫主要以新生长的香脂冷杉（冷杉）、红云杉（云杉）、白色云杉（云杉）和黑云杉（云杉）为食。有时它以其他针叶树为食，如东部落叶松（Larix lancina）、东部铁杉（Tsuga canadensis）、恩格曼云杉（Picea engelmannii）、亚高山冷杉（Abies lasiocarpa）和东部白松（Pinus strobus）。
The spruce budworm, Choristoneura fumiferana (Clemens), (Lepidoptera: Tortricidae) was first described from specimens collected in Virginia,17 but this native insect occurs primarily in the northern boreal forest from Newfoundland west to the McKenzie River near 66°N.53 The most extensive and destructive outbreaks have occurred in the maritime provinces (New Brunswick, Nova Scotia, Newfoundland), Quebec, Ontario, Maine, and the Great Lakes states. This defoliator feeds primarily on the new growth of balsam fir (Abies balsamea), red spruce (Picea rubens), white spruce (Picea glauca), and black spruce (Picea mariana). Sometimes it feeds on other conifers, such as eastern larch (Larix lancina), eastern hemlock (Tsuga canadensis), Engelmann spruce (Picea engelmannii), subalpine fir (Abies lasiocarpa), and eastern white pine (Pinus strobus).28,47
