摘　　要：为了解秦岭国家植物园天牛科昆虫物种组成和区系状况,2022-2023年采用样线网捕法、灯诱法、文献检索等方法,对园区的天牛科昆虫进行了调查研究.结果表明,秦岭国家植物园分布有天牛科昆虫6亚科64属90种,较«秦岭植物园科学考察报告»所记录的39种新增了51种.其中沟胫天牛亚科种数最多,有30属43种,占总种数的47.78%,其次为天牛亚科,有17属26种,占28.89%;锯花天牛亚科仅有1属1种,占1.11%.小粉天牛属(MicrolenecamptusPic,1925)和二点小粉天牛(M.obsoletus Fairmaire,1888)为秦岭地区和陕西省新记录属、种;修订原错误记录1种,即原记录的桑粒肩天牛(Aprionagermari)实为皱胸粒肩天牛(A.rugicollis).区系组成上,以广布种为主,兼有一定的东洋种和古北种;在我国昆虫地理区划中分布型组成较为复杂,共有22个分布型,90%的物种为跨区分布,以华中区种类为主体,并与华南区和华北区存在密切联系.In order to understand the species composition and fauna of longicorn beetles in Qinling National Botanical Garden,the longicorn beetles were investigated from 2022 to 2023 using the methods of sample line net capture,light trap and literature search.The results showed that there were 90 species,64 genera and 6 subfamilies.Compared with the 39 species recorded in the Scientific Investigation Report of Qinling Botanical Garden,51 species were added.Among them,the number of species of Lamiinae is the largest,with 30 genera and 43 species,accounting for 47.78%of the total number of species,followed by Cerambycinae with 17 genera and 26 species,accounting for 28.89%,and Dorcasominae with only 1 genera and 1 species,accounting for 1.11%.Microlenecamptus and M.obsoletus were newly recorded genera and species in Qinling Mountains and Shaanxi Province,and one species record was revised.In terms of fauna composition,it is dominated by widespread species,with some Oriental species and Palaearctic species.The composition of distribution types in China's insect geographical divisions is more complex,with a total of 22 distribution types,90%of the species are cross-regionally distributed,mainly in Central China,and are closely related to South China and North China.
