9726587 Wheeler Testing Relationships ofHeteroptera (Insecta) with DNA Sequence Data The Heteroptera or true bugs, a suborder of the Hemiptera, represent what is probably the largest group of insects with incomplete development. The approximately 40,000 species placed in the taxon demonstrate a tremendous range of life styles and biotic associations. Uniquely among insects, some can walk on the surface of water, while some of the truly aquatic forms can extract air directly from water through the use of a plastron. Many are predaceous on other insects, others feed on plants, including seeds, juices, and cell contents, and at least three lineages are vertebrate parasites. Among this great variety of feeding types are found species of importance to agriculture and public health. DNA sequence data from four nuclear and mitochondrial loci (18SrDNA, 28SrDNA, mt 16SrDNA, and mtCOI) will be gathered and combined with morphological information to test 1 ) existing theories of higher-level heteropteran evolution and 2) notions of family-group relationships within five of the seven recognized higher groups.

9726587惠勒 利用DNA序列数据检验异翅目昆虫的亲缘关系 半翅目的一个亚目，异翅目或真蝽，可能是发育不完全的昆虫中最大的一个类群。该分类群中约有40，000个物种，展示了巨大的生活方式和生物关联。在昆虫中独一无二的是，有些可以在水面上行走，而一些真正的水生形式可以通过使用腹甲直接从水中吸取空气。许多以其他昆虫为食，其他以植物为食，包括种子，果汁和细胞内容物，至少有三个谱系是脊椎动物寄生虫。 在这些种类繁多的饲养类型中，发现了对农业和公共卫生重要的物种。来自四个核和线粒体基因座（18 SrDNA，28 SrDNA，mt 16 SrDNA和mtCOI）的DNA序列数据将被收集并与形态学信息相结合，以测试1）现有的高级异翅目进化理论和2）在七个公认的高级群体中的五个群体中的家族-群体关系的概念。
