川硬皮肿腿蜂雌蜂中枢神经系统解剖结构

Anatomy of central nervous system of female Scleroderma sichuanensis(Hymenoptera:Bethylidae)

应用解剖镜研究了川硬皮肿腿蜂Scleroderma sichuanensis雌蜂中枢神经系统的结构与分布.结果表明:川硬皮肿腿蜂中枢神经系统由脑和腹神经索组成,前中后脑分化不很明显,中脑相对于前后脑发达;腹神经索包括咽下神经节、2对胸神经节、5对腹神经节及纵贯各神经节的神经索;胸神经节位于前胸和中胸,腹神经节位于第1～6腹节节间膜下方.最后,比较了川硬皮肿腿蜂与其他膜翅目昆虫脑和咽下神经节的差异.

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 [Ch, 3 fig. 10 ref.]
