Pterygota are traditionally divided in two lineages, the "Palaeoptera" and Neoptera. Despite several efforts neither morphology nor molecular systematics have resolved the phylogeny of the pterygote insects. Too few markers have yet been identified for adequately tracking mesozoic-aged divergences. We tested the Elongation factor-1alpha for its phylogenetic value in pterygote insect systematics. This highly conserved nuclear protein-coding gene has previously been reported to be useful in other groups for phylogenetic analyses at the intraordinal level as well as at the interordinal level. The analyses suggest that EF-1alpha DNA sequences as well as intron positions provide informative markers for pterygote phylogenetics.
有翅亚纲传统上分为两个谱系，“古翅类”和新翅类。尽管有几次努力，形态学和分子系统发育都没有解决有翅昆虫的系统发育。用于充分追踪中生代分歧的标记物还太少。我们测试了伸长因子 1α 在有翅昆虫系统发育中的系统发育价值。这个高度保守的核蛋白编码基因之前已被报道在其他群体中用于种内水平和种间水平的系统发育分析有用。分析表明，EF-1α DNA 序列和内含子位置为有翅亚纲系统发育提供了有用的标记。
