小蜂总科昆虫大多数种类是许多农林牧业重大害虫的天敌，对其资源进行广泛深入调查， 开发和利用其中的优势寄生蜂种类，对控制害虫种群数量、防治潜在害虫的爆发、维持生态平 衡有重要意义。阿尔金山国家级自然保护区属高原生态系统的保护区，其高寒、高旱、强紫外线、低氧、强风的极端环境，孕育了独特的昆虫资源。但至今为止，对该地区小蜂总科昆虫资源的调查研究尚未有人涉及。本研究旨在广泛深入调查阿尔金山国家自然保护区小蜂资源，将形态分类与DNA条形码技术相结合，准确描述鉴定小蜂种类，发现、描述新物种，摸清阿尔金山小蜂资源和区系分布特点，丰富我国小蜂总科昆虫的基础资料，为将来进一步探索小蜂总科系统发育提供基础数据，同时为探索高寒环境下小蜂抗逆机理、以及高原农业害虫生物防治提供科学依据。

Most species of Chalcidoidea are parasitoids of other insects, including some serious pests in agriculture and forestry. Therefore, it is important to exploit as well as utilize these beneficial parasitoids in controlling pest population, preventing the explosion of potential pests and maintaining ecosystem balance. Arjin Mountain National Nature Reserve is an alpine ecosystem conservation area. Its alpine, high drought, intense ultraviolet, low-oxygen, high winds and other weather features, gives birth to a unique insect resource. But so far, few people study on the chalcidoids in this region. Based on previous research of chalcidoids resources in the basin desert and oasis environment from Xinjiang, this project aims to identify the species of the chalcidoids in this reserve, discover and describe some new taxon with the method of combination of traditional classification and DNA barcoding technology, to explore the chalcidoids resources of Arjin Mountain national nature reserve. Investigating the resource and fauna of the chalcidoids on this area can enrich the basic data of chalcidoids in China and also provide basic data for further study of phylogeny of chalcidoids in future. Additionally, the results will provide a scientific data for the research on stress resistance mechanism of the parasitoids and its biological control on highland agricultural pests in alpine region.
