Bamianshan is one of the newly established nature reserves in Hunan Province. The study on the composition of insect community in this area showed that the insect geographical division belongs to the southern subtropical tea-plantation in the eastern part of Zhejiang Province, the southern mountainous province of Zhejiang and Fujian. The origin of the fossils belongs mainly to the China-Himalayas (Eastern floristic) and many members of the Indian-Malaysian floristry. The insects in this area are mainly under the control of the secondary broadleaf forest community. There are many kinds of insects, but their numbers are small. At the same time, their natural enemies are rich in resources, complicated and stable in structure.
