FMRFamide-like immunoreactivity in the ventral ganglion of the fly Sarcophaga bullata: metamorphic changes.
1. Localization of FMRFamide-like immunoreactivity was examined in the ventral ganglion of the fly Sarcophaga bullata using the indirect immunofluorescent method. 2. There are six large cells in the thoracic ganglion which are highly immunoreactive at all stages of development. 3. During metamorphosis the thoracic FLI neurons shift their position from ventrolateral to mid-ventral position and their axons terminate and elaborate a highly immunoreactive dorsal neural sheath. 4. It is suggested that the dorsal neural sheath may function as a neurohaemal organ from which FMRFamide-like substances may be released into the haemolymph to act as neurohormones.
