Abstract
The structure and distribution of central nervous system of female Scleroderma sichuanensis were studied with dissecting microscope .The results showed that the central nervous system consisted of brain and ventral nervecord.There were unobvious difference among protocerebrum , deutocerebrum and tritocerebrum .The protocerebrum was the biggest part of the brain .Ventral nerve-cord consisted of suboesophageal ganglion , two pairs of thoracic ganglia, five pairs of abdominal ganglia and connectives between ganglia .Thoracic ganglia were situated in prothorax and mesothoraxt and abdominal ganglia were situated below the peritoneum of 1 -6 belly .The brain and the suboesophageal ganglion of the Scleroderma sichuansis were compared with those of other Hymenoptera species .
