Abstract
Evidence demonstrating that the neuroendocrine system (brain, corpus cardiacum, and corpus allatum) of the tobacco hornworm, Manduca sexta (L.), contains a peptide that is gastrin-like in its antigenicity, size, and susceptibility to degradative enzymes is presented. No immunoreactive gastrin was found in gut extracts from four species of insects. These results suggest the existence of a peptide in insect nervous tissue having structural similarities to vertebrate gastrin.
