Termination of Antennal Receptor Cells in Subesophageal Ganglion of Cabbage Butterfly Pieris rapae (Insecta, Lepidoptera)

This study has been performed to investigate normal synaptic organizations in the subesophageal ganglion and terminaiion of antennal receptor cells in the ipsilateral subesophageal gan91ion of Pieris rapae. The various normal synaptic organizations in subesophageal ganglion could be differentiated into the five types. The proximal removal of a left antenna resulted in the weakly-dark, semidark and dark degenerations in the type I bostons of the ipsilateral subesophageal ganglion. Therefore, it was concluded that the axon terminals of the receptor cells projecting from the antenna into the brain form the type 1 synapses together with the dendrites in the ipsilateral subesophageal ganglion.
