摘　　要：桑天牛（Ａｐｒｉｏｎａｇｅｒｍａｒｉ（Ｈｏｐｅ））成虫中枢神经系统由脑、咽下神经节、腹神经索组成，前、中、后脑分化明显。腹神经索包括三对胸神经节、三对腹神经节及纵贯各神经节的神经索。后胸神经节由后胸，第１、２腹节神经节合并而成。第三腹神经节由第５～９腹节神经节合并而成。口交感神经系统由前走神经、上唇神经、额神经节、逆走神经、嗉囊神经节、前肠神经等组成，无脑下神经节。腹交感神经并入腹神经节及其侧神经。尾交感神经源于腹末最后一个神经节，包括１６～１８支侧神经。The central nervous system of adult Apriona germari (Hope) consisted of brain, suboesophageal ganglion and ventral nerve cord There were obvious differentiations among protocerebrum, deutocerebrum and tritocerebrum Ventral nerve cord consisted of three pairs of thoracic ganglia, three pairs of abdominal ganglia and the connectives between ganglia The present metathoracic ganglion was fused with the original metathoracic ganglion, the first and the second abdominal ganglion The present third abdominal ganglion was fused by the abdominal ganglia, belonging to segments 5～9 The stomatogastric nervous system consisted of procurrent nerve, labral nerve, frontal ganglion, recurrent nerve, ingluvial ganglion and fore gut nerve The hypocerebral ganglion was absent The ventral sympathetic nervous system was merged into the abdominal ganglia and their lateral nerves The caudal sympathetic nervous system originating from the last abdominal ganglion consisted of sixteen or eighteen pieces of lateral nerves
