蚕蛾科昆虫物种丰富，属于重要的经济昆虫类群。然而，其亚科间、属间的系统发育关系仍然知之甚少，许多物种的鉴定也很困难，这些问题严重阻碍了蚕桑业等相关领域的发展。鉴于此，本项目以中国及其毗邻地区蚕蛾科昆虫为主要研究对象，基于成虫外部形态特征分析，深入幼期形态学特征及其生物学特性研究，充分发挥国际合作优势，收集我国及周边地区还未记录的物种材料，运用高通量测序技术，获取各属代表种的形态数据和分子数据。基于现代支序系统学研究方法，重建客观清晰的蚕蛾科昆虫系统发育框架，阐明其亚科、属的系统分类地位。在ML/BI拓扑结构框架下，结合祖先特征重建技术，整合形态特征、生物学特性及分子数据，明确疑难属内的物种界定特征并阐明其演化历程。该项目研究结果将为生物多样性保护及绢丝资源昆虫利用等提供良好的科学依据和理论指导。

The family Bombycidae is a species-rich and economically important insect group. However, the phylogenetic relationships among its subfamilies and genera are still poorly understood, and the identification of many species is difficult. These problems seriously hinder the development of research in the fields of sericulture, agriculture and pest management. Hence, this project on Bombycidae from China and its adjacent areas will investigate the morphological characters of adults and larvae, and their biological traits. It will also utilize international collaborations and high-throughput sequencing technology to build up a reference and tissue collection of species outside of China, and to generate first large-scale molecular data for the family. Based on morphological and molecular data, this project will reconstruct the phylogenetic framework of Bombycidae and clarify the systematic status of the subfamilies and genera. It will further provide defining characters and identification keys for problematic genera, and explain the evolutionary of key characters by integrating morphological, molecular and biological data, and reconstructing ancestral characters. This project will provide a sound scientific basis and theoretical guidance for the protection of biodiversity and the utilization of silk moths in China.
