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.

半翅总目昆虫类群（hemipteroid insect orders）包含半翅目（Hemiptera）、啮虫总目（Psocodea）与缨翅目（Thysanoptera），是昆虫中多样性极为丰富的类群，已描述物种超过12万种。该类群涵盖诸多具备重要生态、经济或医学价值的物种，且其内部多数演化支均具有刺吸式口器。目前该类群的核心系统发育关系尚未得到充分研究。本项目的核心目标之一，是针对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。
