Hemipteroid Insect Assembling the Tree of Life Project

The hemipteroid insect orders (Hemiptera, Psocodea, and Thysanoptera) are a diverse group among the insects, including over 120,000 described species. This group contains many species of ecological, economic, or medical importance, and many of the lineages within this group have piercing-sucking mouthparts. The backbone phylogenetic relationships of this group have not been well studied. One of the major goals of this project is to combine transcriptome and genome sequences (using Illumina sequencing technology) for representatives of all the major lineages of this group and most families to construct a well resolved phylogenetic tree.

半翅类昆虫总目（Hemipteroid insect orders）涵盖半翅目（Hemiptera）、啮虫总目（Psocodea）与缨翅目（Thysanoptera）三个目级类群，是昆虫纲中物种多样性极高的类群之一，已描述物种逾12万种。该类群包含诸多兼具重要生态、经济与医学价值的物种，且多数演化支具有刺吸式口器。目前针对该类群的核心系统发育关系，相关研究仍较为薄弱。本项目的核心目标之一，是选取该类群所有主要演化支以及绝大多数科的代表物种，整合转录组与基因组序列（采用Illumina测序技术），以构建分辨率优良的系统发育树。
