昆虫通过传播疾病、消耗农作物和破坏基础设施，给人类社会带来了一些最大的发展挑战。尽管入侵昆虫造成了巨大的人力和财力损失，但对其影响的成本估计仍然是零星的，空间上不完整，质量也有问题。在这里，我们编制了一个全面的入侵昆虫的经济成本数据库。根据所有报告的商品和服务估计，入侵昆虫每年在全球造成至少700亿美元的损失，而相关的健康成本每年超过69亿美元。总成本随着估计数的增加而增加，尽管许多最严重的成本已经估计出来（特别是与人类健康有关的成本）。缺乏专门的研究，特别是对可复制的商品和服务的估计，意味着严重低估了全球成本。气候变化导致的全球变暖、人口密度上升和国际贸易加剧将使这些代价高昂的昆虫扩散到新的地区，但通过加强监测、遏制和公众意识，可以节省大量资金。 入侵昆虫造成许多经济成本，例如通过消耗作物和传播疾病。Bradshaw等人编制了一个入侵昆虫成本数据库，并保守估计全球每年的成本（以2014年的美元等值计算）至少为700亿美元的商品和服务以及69亿美元的人类健康。
Insects have presented human society with some of its greatest development challenges by spreading diseases, consuming crops and damaging infrastructure. Despite the massive human and financial toll of invasive insects, cost estimates of their impacts remain sporadic, spatially incomplete and of questionable quality. Here we compile a comprehensive database of economic costs of invasive insects. Taking all reported goods and service estimates, invasive insects cost a minimum of US$70.0 billion per year globally, while associated health costs exceed US$6.9 billion per year. Total costs rise as the number of estimate increases, although many of the worst costs have already been estimated (especially those related to human health). A lack of dedicated studies, especially for reproducible goods and service estimates, implies gross underestimation of global costs. Global warming as a consequence of climate change, rising human population densities and intensifying international trade will allow these costly insects to spread into new areas, but substantial savings could be achieved by increasing surveillance, containment and public awareness. Invasive insects impose many economic costs, for example by consuming crops and spreading disease. Here, Bradshaw et al. compile a database of the costs of invasive insects and conservatively estimate that the yearly global cost (in 2014-equivalent US dollars) is at least $70 billion for goods and services and $6.9 billion for human health.
