The lack of a reliable family tree for the extraordinarily diverse beetle family Curculionidae (true weevils) has impeded taxonomic, systematic and applied research on weevils. This project will reconstruct the family tree of Curculionidae and establish a timeframe for weevil diversification by analyzing genomic and morphological (anatomical) data. The genomic data gathered will consist of DNA sequences from 1,000 species representing all major groups of weevils, obtained via an approach called anchored phylogenomics. This will be one of the first applications of this new method for gathering phylogenomic data in insects.Curculionidae contains 51,000 named species and is one of the largest families of animals on Earth. Because of their intimate and often highly specialized interactions with plants and fungi, Curculionidae are among the most significant pests of agriculture and forestry worldwide, and some of the most abundant insects on Earth. This project will clarify the interrelationships of all major groups of weevils for the first time. The resulting family trees will be used to test long-standing hypotheses about weevil relationships and evolution, and will contribute to resolving the taxonomic problems that both pervade the internal higher classification of weevils and impede research on economically and ecologically important weevil species.

缺乏可靠的家谱，用于多样化的甲虫家庭姜黄科（True Weevils）阻碍了对象鼻虫的分类，系统和应用研究。该项目将通过分析基因组和形态学（解剖学）数据来重建姜黄科的家谱，并建立象鼻虫多样化的时间表。收集的基因组数据将由来自代表所有主要象鼻虫组的1,000种的DNA序列组成，该序列是通过一种称为锚定系统基因组学的方法获得的。这将是这种新方法在昆虫中收集系统基因组数据的第一个应用之一。Curculionidae含有51,000种命名物种，并且是地球上最大的动物家族之一。由于它们与植物和真菌的亲密且经常高度专业化的相互作用，因此是全世界最重要的农业和林业的害虫之一，也是地球上一些最丰富的昆虫。该项目将首次阐明所有主要象鼻虫的相互关系。由此产生的家谱将用于检验有关象介关系和进化的长期假设，并将有助于解决分类问题，这些分类问题既弥补了象鼻虫的内部更高分类，又阻碍了对经济和生态上重要的象鼻虫物种的研究。
