Antisera against a variety of vertebrate and invertebrate neuropeptides were used to characterize neurons with somata in the pars intercerebralis (PI), pars lateralis (PL), and subesophageal ganglion (SEG), designated as PI neurons, PL neurons, and SEG neurons, respectively, all of which project to the retrocerebral complex in the blow fly, Protophormia terraenovae. Immunocytochemistry combined with backfills through the cardiac-recurrent nerve revealed that at least two pairs of PI and SEG neurons for each were FMRFamide-immunoreactive. Immunoreactivity against [Arg7]-corazonin, beta-pigment-dispersing hormone (beta-PDH), cholecystokinin8, or FMRFamide was observed in PL neurons. Immunoreactive colocalization of [Arg7]-corazonin with beta-PDH, [Arg7]-corazonin with cholecystokinin8, or beta-PDH with FMRFamide was found in two to three somata in the PL of a hemisphere. Based on their anatomical and immunocytochemical characteristics, PI neurons were classified into two types, PL neurons into six types, and SEG neurons into two types. Fibers in the retrocerebral complex showed [Arg7]-corazonin, beta-PDH, cholecystokinin8, and FMRFamide immunoreactivity. Cholecystokinin8 immunoreactivity was also detected in intrinsic cells of the corpus cardiacum. The corpus allatum was densely innervated by FMRFamide-immunoreactive varicose fibers. These results suggest that PI, PL, and SEG neurons release [Arg7]-corazonin, beta-PDH, cholecystokinin8, or FMRFamide-like peptides from the corpus cardiacum or corpus allatum into the hemolymph, and that some PL neurons may simultaneously release several neuropeptides.
