Summary
The distribution of FMRFamide immunoreactive neurones in the ventral nerve cord of the locust, Schistocerca gregaria, is described. These neurones are found only in the suboesophagael and thoracic ganglia, although immunoreactive processes are found in the neuropils of the abdominal ganglia. Many of these neurones also react with an antiserum raised against bovine pancreatic polypeptide (BPP), but this antiserum also reveals another population of cells in the abdominal ganglia. The staining obtained with the BPP antiserum is blocked by preabsorption of the antiserum with FMRFamide; the converse is not true: FMRFamide-like immunoreactivity is not suppressed by preincubation with BPP. These results suggest that there are at least two endogenous peptide antigens in the locust nerve cord: one is found in cells of the suboesophageal and thoracic ganglia, and the other is found in cells of the abdominal ganglia.
