9521925 Irwin The Therevidae (Insecta: Diptera: Asiloidea) is a speciose group of flies inhabiting particularly fragile, xeric environments. The family radiated in warm desert regions of the world, and its species are particularly abundant in Australia, western North America, southwestern South America, the Mediterranean area, and southwestern Africa. Larvae are voracious predators of soil-dwelling arthropods. Thus, these flies are critical to the functioning of natural and managed systems, are potential control agents of fossorial pests, and are probable indicators of environmental heterogeneity and productivity. Yet, worldwide, the family Therevidae is among the poorest known and least understood of the flies because the larvae are difficult to locate and the adults are secretive, frequenting habitats rarely sampled. The family contains an estimated 3,000 species worldwide, of which fewer than one-third have been described. The poor state of knowledge of this family is a major constraint to its potential use for protecting agriculture and for gauging habitat health. %%% This grant proposes to further the task of comprehensively elucidating the world Therevidae. The team that has been assembled is talented, complementary in function, and well integrated in approach. The grant will create and manipulate comprehensive databases of specimen character, collection, and geographic information, produce monographic treatments of genera, initiate a higher level classification of the family, organize and disseminate knowledge contained in databases and monographs to targeted clientele, and educate five next-generation Diptera systematists through a combination of formal and informal training, including participation in field expeditions. Molecular character sets will test and extend hypotheses derived from morphological character analyses. Diskettes and CD-ROMs that contain descriptions and expert keys will be disseminated to museum curators. A larger audience will be targeted for more ge neralized information through a home page on WWW, where anyone with access to the Internet can browse and learn about the Therevidae. ***

9521925欧文该Therevidae（昆虫纲：双翅目：Asiloidea）是一个speciose组苍蝇栖息在特别脆弱，干旱的环境。 该科在世界温暖的沙漠地区辐射，其物种在澳大利亚，北美西部，南美洲西南部，地中海地区和非洲西南部特别丰富。 幼虫是土壤节肢动物的贪婪捕食者。 因此，这些苍蝇是至关重要的自然和管理系统的功能，是潜在的控制剂的fossorial害虫，并可能是环境异质性和生产力的指标。 然而，在世界范围内，科Therevidae是最贫穷的已知和最不了解的苍蝇之一，因为幼虫很难找到，成年人是秘密的，经常栖息地很少采样。 全世界估计有3,000种，其中不到三分之一被描述。 该家庭的知识水平低下是其在保护农业和衡量栖息地健康方面的潜在用途的主要限制因素。 %此补助金建议进一步全面阐明世界的任务。 组建的团队才华横溢，功能互补，方法统一。 这笔赠款将创建和操作标本特征，收集和地理信息的综合数据库，制作属的专题处理，启动更高级别的科分类，组织和传播数据库和专题论文中包含的知识给目标客户，并通过正式和非正式培训相结合，包括参加实地考察，教育下一代双翅目系统学家。 分子特征集将测试和扩展来自形态特征分析的假设。 将向博物馆馆长分发载有说明和专家钥匙的软盘和光盘。 通过万维网上的主页，将有更多的读者获得更一般化的信息，任何人都可以访问互联网，浏览和了解锥虫科。 ***
