Diversity of Longicorn Beetles in Lishan National Nature Reserve,Shanxi,China
In order to understand the occurrence status,population structure and distribution of longicorn beetles in Lishan National Nature Reserve in south of Shanxi province,China.Four habitat types(Broad-leaved forest belt.Co-niferous and broad-leaved forest belt.Sparse forest shrub belt.Shrub farming belt.)were selected from four pre-cincts(Xiachuan precincts.Ligeda precincts.Lishan precincts.Dahe precincts.)in the nature reserve to investigate the diversity of longicorn beetle.The results of the diversity analysis show that the reserve of the longicorn beetle in-sects belonging to 120 species of 81 genera,in 6 subfamilies,accounting for 12.16%and 3.05%of the known gene-ra and species in China respectively,among which Cerambycinae has the largest number of species and Lepturinae has the largest number of individuals,and fifty-six species are newly recorded to Shanxi province.According to the coefficient of genus-species ratio,single-species genera account for a large proportion,implying that single-species are dominant within the genus of Cerambycidae in this reserve.Diversity analysis shows:Lishan precincts has the highest richness index,The order from high to low values in the Pielou's eveness index and Shannon-Wiener index is Ligeda precincts>Dahe precincts>Lishan precincts>Xiachuan precincts,the Simpson index is Xiachuan precincts>Lishan precincts>Dahe precincts>Ligeda precincts.Sparse forest shrub belt has the highest richness index,The or-der from high to low values in the Pielou's eveness index and Shannon-Wiener index is Shrub farming belt>Sparse forest shrub belt>Coniferous and broad-leaved forest belt>Deciduous broad-leaved forest belt,the Simpson index is Deciduous broad-leaved forest belt>Coniferous and broad-leaved forest belt>Sparse forest shrub belt>Shrub farm-ing belt.The faunal distribution pattern is mainly characterised by species shared by the Palearctic and Oriental,ac-counting for 84.17%of the species in the region.There are a total of 30 zone types belonging to the geographical di-vision of insects in China,with North China and Central China as the main body,and closely related to Southwest China.
