  • The present paper deals with vertical distribution of Vespoidea and analeysis of the fauna in Yunnan.Yunnan plateau took shape through the ascent by the orogenic movement of the Tertiary and Quaternary period.The geographical,climate and vegetation of Yunnan are very complicatod.The different climates,soil and vegetation on different altitudes of the plateau exert strong influencee on the insects in their breeding and multiplication.The elevation and latitudes,in authors point of view,are important factor that affect the distribution of insects.Their distributions are related to elevation and latitudes-a flight of stairs from low to high.The more latitude is to the north,the more significantly vary the distribution of insects.On the basis of the distribution characterstics of insects,the physical geography,landform,climate and vegetation of the place,Yunnan plateau may be divided into 5 vertical zones:(1)Zone of the river valley and tropical rainforest and mousoon forest (76.4-1400 m),(2)Zone of mountainous region subtropical and evergreen deciduous leaves and broadleaf forest (1400-1900 m),(3)Zone of low mountain subtropical and evergreen broadleaf forest (1900-2300 m),(4)Zone of middle warm mountain and mixed forest (2300-2700 m),(5)Zone of subalpine coniferous forest (2700-3900 m).Among the 122 species of wasps collected,20 species (16.4%) belong to tropical species,and 86 species (70.5%) to subtropical species,and 9 species (7.4%) to palaearctic species,and the rest of the tolal number are transregional species (5.7%).On the basis of the results of our research,Yunnan should belong to the oriental region,86.9% of the vespoidea fauna in Yunnan region is oriental species.Only a very small part of the species are palaearctic and transregional.
