摘要：为了摸清青藏高原缨翅目Thysanoptera昆虫物种组成及其区系特点，本研究针对该地区已知缨翅目昆虫3科35属78种进行了初步的区系分析。结果发现：青藏高原缨翅目昆虫在世界动物地理区系中突出为中国-日本界成分（21.79%），其次为中国-日本界+东洋界成分（19.23%）；青藏高原缨翅目昆虫在中国动物地理区系中各属种区系型共有7型28式，突出为西南区成分（67.95%），其次为青藏区成分和华中区成分（52.56%）；特有种共计16属24种，主要分布在西南区（17种）和青藏区（9种）。基于青藏高原地区缨翅目昆虫区系特点，其结果支持了青藏高原归属于古北界、东洋界和中日界3个动物界内。本研究有助于全面了解青藏高原昆虫的物种多样性，同时为青藏高原缨翅目昆虫资源、害虫综合防治等研究提供指导。

Abstract: For making clear the species composition and fauna distribution characteristics of Thysanoptera in Qinghai-Tibet Plateau (QTP), this study preliminarily analyzed the fauna of thrips based on 78 species belonging to 35 genera and three families. The results showed that in the zoological fauna of the world, the Sino-Japanese (21.79%) was prominent of Thysanoptera insects in the QTP, followed by the Sino-Japanese+Oriental (19.23%). There are seven patterns and 28 types in genera and species distribution in the zoogeographic fauna of China of Thysanoptera insects in the QTP, the components from the Southwest region are prominent (67.95%), followed by those from the Qingzang region and the Central China region (52.56%). There are 24 species of 16 genera are endemic to QTP, mainly distributed in Southwest region (17 species) and Qingzang region (9 species). Based on the characteristics of the Thysanoptera fauna in the QTP, the results support that QTP should belong to the Palaearctic, Oriental and Sino-Japanese. The aims of this study are to know the insect diversity in QTP, and to guide for investigating of Thrips resources and controlling the harmful species.
