LSC: Axenic Culture Collection of Insect Gut Fungi (Harpellales) and Other Symbionts of Arthropods: Incorporating the Isolates into Other Culture Collections

半翅目(齐格菌目，毛霉目)是生活在水生昆虫幼虫后肠内的真菌共生体，包括下双翅目，如黑蝇、蚊子、吸虫等5个科，以及石蝇(直翅目)、脉翅目(麻蝇目)、鞭翅目(毛翅目)幼虫或若虫的幼虫或若虫阶段，甲虫幼虫(鞘翅目)和等足目(等足目)很少。这种全球范围内与昆虫的联系从共生到互惠或寄生，取决于真菌及其宿主的种类和发育阶段。这一独特的收集包括代表8属43种的250多个分离物，以及目前尚未鉴定的最大属Smittium的44个分离物。该奖项提供资金，将这些独特的内生共生菌的培养纳入包括美国农业部在内的其他机构的藏品中，从而使研究人员和教师在未来很长一段时间内都能使用它们。关于收藏的信息和一本书长的关于毛霉菌生物学和分类学的专著的链接，一个关于肠道真菌研究的全球参考清单，一个不断更新的互动插图所有物种的检索表，以及一个目前正在完成的大型数据库，可以在www.nhm.ku edu/~真菌上找到。

Harpellales (Zygomycota, Trichomycetes) are fungal symbionts that live in the hindgut of larval aquatic insects, including lower Diptera (Nematocera) such as black flies, mosquitoes, midges, and five other families, and the larval or nymphal stages of stoneflies (Plecoptera), mayflies (Ephemeroptera) caddisflies (Trichoptera), and rarely in beetle larvae (Coleoptera) and isopods (Isopoda). This worldwide association with insects ranges from commensalistic to mutualistic or parasitic, depending upon the species and the stages of development of both the fungi and their hosts. This unique collection consists of more than 250 isolates representing 8 genera and 43 species, plus more than 44 isolates of currently unidentified species of the largest genus, Smittium. This award provides funds to incorporate the cultures of these unique endosymbionts into collections at other institutions including the USDA, thereby making them available to researchers and teachers well into the future. Information about the collection and links to a book-length monograph on the biology and systematics of Trichomycetes, a worldwide list of references to studies on gut fungi, a constantly updated interactive illustrated key to all species, and a large database that is currently being completed can be found at www.nhm.ku.edu/~fungi.
