Bark beetles are among the most damaging pests, and a diverse group of insects which are difficult to identify. This project will revise the classification and evolutionary history of one of the largest and most important bark beetle groups: Cryphalini, the Pygmy Borers. The project will 1) revise the classification of Cryphalini genera using a molecular phylogeny, 2) analyze populations of putatively global cryphaline species (some of the most widespread insects on Earth) to test whether they are true species or clusters of cryptic species, and 3) reconstruct the evolution of genome copy number in Pygmy Borers (in some genera, males have only one copy of each chromosome), and test whether deviations are associated with manipulative bacterial parasites. Our approach integrates next-generation sequencing, automated matrix-based taxonomy, and a large global network of collaborators, including ?citizen collectors?.Our high-throughput methodology represents a new cost-efficient approach to diverse but understudied groups of organisms. Non-academics will benefit from the new identification capacity. A single cryphaline species (i.e., the Coffee Berry Borer) causes $500,000,000 annual damages, yet quarantine officers have no tools to distinguish it from other cryphalines. The broad public will benefit from a new Citizen Science project ?Bark beetles in your backyard?.

树皮甲虫是最具破坏性的害虫之一，也是一群难以识别的昆虫。该项目将修订最大和最重要的树皮甲虫类群之一的分类和进化历史：Cryphalini，俾格米蛀虫。该项目将：1)使用分子系统发育法修订Cryphalini属的分类；2)分析假定的全球cryphaline物种（地球上最广泛分布的一些昆虫）的种群，以测试它们是真正的物种还是隐藏物种的集群；3)重建侏儒螟虫基因组拷贝数的进化（在某些属中，雄性每条染色体只有一条拷贝），并测试偏差是否与可操纵的细菌寄生虫有关。我们的方法集成了下一代测序，自动化基于矩阵的分类法，以及一个庞大的全球合作者网络，包括？公民收藏家吗?。我们的高通量方法代表了一种新的成本效益的方法，以不同的，但研究不足的生物群体。非学者将受益于新的识别能力。一种单独的隐孢子虫（即咖啡浆果虫）每年造成5亿美元的损失，但检疫官员没有办法将其与其他隐孢子虫区分开来。广大公众将从一个新的公民科学项目中受益？在你的后院叫甲虫？
