9978026Dietrich and Deitz This Partnership for Enhancing Expertise in Taxonomy (PEET) award supports a team approach to taxonomic monography, student training, and databasing directed toward the Membracoidea group of insects, with about 25,000 published species names and estimates up to 250,000 of the actual number of species worldwide. These are the leafhoppers and treehoppers, insects with piercing and sucking mouthparts that feed on plant sap; many of these are pests in agricultural and agro-forestry systems or serve as vectors of plant disease. Despite their great diversity and ecological significance, the taxonomy, classification, and understanding of phylogenetic relationships in this large group of insects are in need of study, and the number of trained specialists is small. This PEET project addresses that need with a program of research and training, including morphological and molecular (DNA sequencing) methods, field expeditions to collect new material, study of existing museum collections, and databasing of information on the taxonomy, phylogeny, geographic distribution, and host affiliations of these insects. The team is led by Christopher Dietrich of the Illinois Natural History Survey and Lewis Deitz of North Carolina State University and includes colleagues at the USDA-Smithsonian (Stuart McKamey) and elsewhere. Pioneering work on the molecular phylogenetics of membracoid insects by the investigators has helped delimit lineages which can serve as challenging but manageable thesis topics for graduate students' research in modern taxonomic monography. Study of extensive museum holdings will be supplemented with field expeditions to regions in Southeast Asia and in Mexico and Central America, where the diversity is poorly represented in existing collections. Morphological and molecular characters will be integrated as part of monographic and revisionary analyses, with attention to synthesizing information from the older literature and resolving nomenclatural problems at species, genus, and family ranks. An extensive program of databasing builds upon computer resources and digital-library expertise at North Carolina State University, which will include an ambitious web-searchable inventory of taxonomic literature on membracoid insects numbering in the thousands of documents.

9978026Dietrich 和 Deitz 这一增强分类学专业知识合作伙伴关系 (PEET) 奖项支持针对膜虫总科昆虫分类学专着、学生培训和数据库的团队方法，该类昆虫已出版约 25,000 个物种名称，估计全世界实际物种数量高达 250,000 个。它们是叶蝉和角蝉，它们是具有刺吸式口器、以植物汁液为食的昆虫。其中许多是农业和农林系统中的害虫或作为植物病害的媒介。尽管它们具有巨大的多样性和生态意义，但这一大类昆虫的分类学、分类和系统发育关系的理解仍需要研究，而且受过培训的专家数量很少。该 PEET 项目通过研究和培训计划来满足这一需求，包括形态学和分子（DNA 测序）方法、收集新材料的实地考察、对现有博物馆藏品的研究以及这些昆虫的分类学、系统发育、地理分布和宿主隶属关系的信息数据库。该团队由伊利诺伊州自然历史调查局的 Christopher Dietrich 和北卡罗来纳州立大学的 Lewis Deitz 领导，成员包括美国农业部史密森学会 (Stuart McKamey) 和其他地方的同事。 研究人员在膜类昆虫分子系统发育学方面的开创性工作有助于界定谱系，这可以作为研究生现代分类学专着研究中具有挑战性但易于管理的论文主题。对大量博物馆藏品的研究将辅之以对东南亚、墨西哥和中美洲地区的实地考察，这些地区现有藏品的多样性表现不佳。形态学和分子特征将作为专题和修订分析的一部分进行整合，重点关注综合旧文献中的信息并解决种、属和科等级的命名问题。一个广泛的数据库计划建立在北卡罗来纳州立大学的计算机资源和数字图书馆专业知识的基础上，其中将包括一个雄心勃勃的可网络搜索的膜类昆虫分类文献目录，数量有数千份文档。
