摘要: 为研究青海省蝗虫区系和生态地理分布问题,于2014年7—10月以及2015—2017年每年的5—10月采用样带法对青海省所有县级行政区划分布的蝗虫进行了系统调查,结合前人的研究基础,统计出青海省蝗虫共有111种,隶属于7科39属。网翅蝗科属、种数均为最多(12属49种),锥头蝗科属、种数均为最少(1属1种)。根据中国动物地理区划,青海省的蝗虫只有古北种(101种)和广布种(10种),所占比例分别为91.0%和9.0%,古北种占有绝对优势。特有种较多(58种),所占比例为52.3%。不同生境中蝗虫种类由多到少依次是:河湟谷地、青东南、青南高原、祁连山地、青海湖盆地、柴达木盆地;河湟谷地与青东南接近程度最高,青南高原与柴达木盆地的相似性系数为最低。

Abstract: To study the aphid flora elements and its eco-geographical distribution in Qinghai Province, from July to October in 2014 and from May to October in 2015-2017, a systematic survey of the locusts was carried out in all the administrative districts of Qinghai Province via belt transect method. Combined with previous studies, a total of 111 species of locusts in Qinghai Province were counted, belonging to 39 genera in 7 families. The number of genera and species of the genus Arcypteridae were the most abundant (49 species of 12 genera), while those of the genus Pyrgomorphldae were the least (1 species in 1 genera). According to the position of locus from Qinghai in Chinese fauna, there were only species of Palaearctic realm (101 species) and Eurytopic species (10 species) distributed in Qinghai Province, accounting for 91.0% and 9.0%, respectively. An absolute advantage was possessed by species of Palaearctic realm. There were more endemic species (58 species), accounting for 52.3%. The order of locus species’ numbers in different habitats was, in descending order, the Hehuang Valley, the southeast of Qinghai, the Qingnan Plateau, the Qilian Mountains, the Qinghai Lake Basin, the Qaidam Basin. The highest proximity existed between the Hehuang Valley and the southeast of Qinghai, while the similarity coefficient between the of the Qingnan Plateau and the of the Qaidam Basin was the lowest.

Key words: locus, fauna, eco-geographical distribution; Qinghai
