This study will produce a phylogeny (family tree) of the 38 flea beetle supra-generic groups and 5 galerucine tribes, which will test three proposed hypotheses of relationships, between the flea beetles and the galerucinae using a comprehensive taxon set and an exhaustive character set from adult and larval morphology and 3 gene fragments from the mitochondrial, nuclear and ribosomal genomes. This phylogeny will also be used to test hypotheses of evolution of jumping behavior, evolution of host- plant choice, Biogeography and geologic age of the flea beetles, and evolution of larval leaf feeding which are of general scientific interest.The flea beetles (Chrysomelidae: Alticinae) together with their sister group, the Galerucinae, are a huge group containing over 12,000 species; they are also extremely damaging to agriculture. The flea beetles are renowned for making "shot holes" in table crops such as potato, broccoli and grapes. The galerucines are infamous for the multi-billion dollar damage to corn and beans. Unfortunately, the taxonomic status of the flea beetles is so confusing that it impedes proper research and pest management. Over 500 described genera of flea beetles are divided into 38 supra-generic tribes, sub-tribes and sections and there is no taxonomic or phylogenetic hypothesis of how these tribes and series are related to one another. This lack of a trust -worthy phylogeny is especially important to pest management, where assumptions about pesticide applications or search for biological control agents are often made based on taxonomic position and where money is often wasted if these assumptions are incorrect.

本研究将产生一个38跳甲超属组和5 galerucine部落，这将测试三个拟议的假设之间的关系，跳甲和galerucinae使用一个全面的分类群集和详尽的字符集从成人和幼虫形态和3个基因片段的线粒体，核和核糖体基因组的亲缘关系（家谱）。这一系统发育也将被用来检验跳跃行为的进化、寄主植物选择的进化、跳甲的生物地理学和地质时代以及幼虫食叶的进化等具有普遍科学意义的假说。（科：高脚蛛亚科）连同它们的姊妹群，Galerucinae，是一个包含超过12，000种的巨大群体;对农业也有很大的危害。跳甲以在马铃薯、花椰菜和葡萄等食用作物上制造“弹孔”而闻名。galerucines因对玉米和豆类造成数十亿美元的损失而臭名昭著。 不幸的是，跳甲的分类地位是如此混乱，它阻碍了正确的研究和害虫管理。 超过500个描述的属的跳蚤甲虫被分为38个超属的部落，亚部落和部分，并没有分类或系统发育的假设，这些部落和系列是如何相互关联的。这种缺乏值得信任的遗传学对于害虫管理尤其重要，其中关于农药施用或生物控制剂的搜索的假设通常是基于分类学位置做出的，并且如果这些假设不正确，则通常浪费金钱。
