Multiple Nuclear Genes for Lepidopteran Phylogenetics

9509174 REGIER该项目将继续研究人员对编码蛋白质的核基因进行测序的努力，这些基因将提供关于主要在昆虫总科（昆虫纲：鳞翅目）、蚕蛾及其亲属之间的更高层次关系的信息。 出于他们自己的目的，他们正在利用序列信息来阐明天蛾科（天蛾和角虫，如烟草角虫）中的亚科关系，并解决天蛾亚科（天蚕亚科）两个部落内的属间关系（巨蚕，如月蛾、天蚕蛾等），阿塔西尼号和萨图尔尼号 在这个过程中，他们正在克隆鳞翅目昆虫的新基因序列，这些新基因应该对广泛关注分子系统发育分析的研究人员有用。 鳞翅目昆虫，包括蝴蝶、跳甲和蛾。 虽然这些昆虫的成虫包括许多收藏家追求的美观成员，但幼虫或未成熟的形式是不太理想的生物。 许多严重的害虫作物，木材，仓储产品，甚至我们的衣服是鳞翅目幼虫。 本项目将提供有关鳞翅目主要类群之间关系的信息。 这些信息在检验关于寄主植物用途或相关性变化的假设以及解释害虫起源的努力中可能具有价值。 它将通过允许对模型和模拟系统的起源、宿主植物特异性等进行假设检验来加强其他研究领域。 ***

9509174 REGIER This project will continue the efforts of the investigators to sequence protein encoding nuclear genes that will be informative about higher level relationships primarily among members of the superfamily Bombycoidea (Insecta: Lepidoptera), the silkmoths and their relatives. For their own purposes they are utilizing the sequence information to elucidate subfamily relationships in the large family Sphingidae (hawk moths and hornworms, such as the tobacco hornworm) and to resolve generic relationships within two tribes of Saturniinae (the giant silkmoths, such as the luna moth, cercropia moth, etc.), the Attacini and the Saturniini. In the process they are cloning Lepidoptera sequence for new genes that should be of utility to a broad community of researchers concerned with molecular phylogenetic analysis. %%% The insect order Lepidoptera, includes the butterflies, skippers, and moths. While adults of these insects include many aesthetically pleasing members sought after by collectors, the larvae or immature forms are much less desirable creatures. Many serious pests of crops, timber, stored products and even our clothing are Lepidoptera larvae. This project will provide information on relationships of major groups of Lepidoptera. Such information can be of value in testing hypotheses about changes in host plant use or associations, in efforts to explain how pests originate. It will enhance other research areas by allowing hypothesis testing about origins of model and mimic systems, host plant specificity, etc.. ***
