本文回顾了57种美国联邦政府列出的昆虫和116种稀有的北美东部鳞翅目昆虫的濒危因素，以确定入侵物种相对于其他15种公认的濒危因素的重要性。入侵植物、群居昆虫（尤其是蚂蚁）和脊椎动物食草和捕食者多次被确定为直接或间接威胁本地昆虫生物多样性的群体。在罕见的北美东部鳞翅目动物中，舞毒蛾（Lymantria dispar）的出现（主要是间接的）造成了普遍的威胁。偏远的岛屿，尤其是那些人流量大的岛屿，受到入侵生物的高度威胁。在最糟糕的情况下，入侵物种的影响会通过群落级联，破坏现有的营养相互联系，改变基本的生态系统特性，改变水文、养分循环、土壤化学、火灾易感性和光效，并引发生物和非生物参数的无数其他变化。入侵蚂蚁和食草昆虫提供了这种昆虫引起的入侵级联的一些最引人注目的例子。
Endangerment factors are reviewed for 57 U.S. federally listed insects and 116 rare eastern North American lepidopterans to determine the importance of invasive species relative to 15 other recognized endangerment factors. Invasive plants, social insects (especially ants), and vertebrate grazers and predators repeatedly were identified as groups directly or indirectly threatening native insect biodiversity. Among rare eastern North American lepidopterans, the (mostly indirect) consequences of the establishment of the gypsy moth (Lymantria dispar) surfaced as a general threat. Remote islands, especially those with high human visitation, stand out as being highly threatened by invasives. In the worst cases, impacts from invasive species cascade through a community and destabilize existing trophic interconnections and alter basic ecosystem properties, changing hydrology, nutrient cycles, soil chemistry, fire susceptibility, and light availability, and precipitate myriad other changes in biotic and abiotic parameters. Invasive ants and herbivorous insects provide some of the most dramatic examples of such insect-induced invasional cascades.
