Species diversity and fauna distribution of Lygus hesperus on the Mongolian plateau were studied. The results showed that: 1. At present, there are 60 species of 23 genera and 5 endemic species of Lygus in the Mongolian Plateau. There are 17 species of Orthotylus Fieber, accounting for 28.3% of the total species. From the distribution countries, there are 36 species of 20 genera in Mongolia, 47 species of 21 genera in Russia (Tuva, Buryat and Chita), 42 species of 20 genera in China (part of Inner Mongolia and part of Xinjiang), 3) There are 47 genera belonging to 13 genera in the Gubei area, accounting for 56.5% and 78.3% of the total respectively. 4. The main body of the Miridae in the Mongolian plateau is Mongolia Among them, 27 species were exclusively distributed in Mengxin District, accounting for 64.3% of the total species. 5. The distribution of Lygus nematodes in Inner Mongolia was 27 species> 26 species in North China> 23 species in Alashan Desert region, 15 species in Nenjiang - West Liaohe plain, 13 species in Daxinanling mountain subregion and 12 species in Ordos plateau sub - region.
