Allatostatin-like immunoreactivity in the optic lobe of the fly Sarcophaga bullata.
An antiserum against Diploptera allastostain 1 (Dip-AST1) was used to map the distribution of allatostain containing neurons in the optic lobes of the fly Saccrophaga bullata. Strongly immunoreacting neurons were found in two areas of the optic ganglia, namely, the medulla and the area between medulla and lobula. These cells were generally interneurons arborizing the base of the medulla. The positive reaction of specific populations of the optic lobe neurons against allatostain antiserum suggests some role for this neuropeptide in the visual physiology of the fly.
