Immunohistochemical surveys revealed the presence of several myotropic neuropeptides as well as serotonin in neurons and endocrine cells of the digestive tract and the thoracico-abdominal ganglion of the horse fly, Tabanus nigrovittatus, and the blow fly, Phormia regina. Injection of exogenous signal molecules and the amine depleter a-methyl-tryptophan significantly altered feeding behavior in these flies.

Species 2: Diptera Calliphoridae Phormia regina (queen blow fly)
Keywords: amine depleter, immunohistochemistry
