Title
Presence of []-corazonin in the central nervous system of a newly isolated albino strain of **Schistocerca gregaria** (Orthoptera : Acrididae) : mass spectrometric and immunocytochemical evidence

Abstract
An inbred strain of a newly isolated spontaneous albino mutant of Schistocerca gregaria (Forsk.) was examined for the presence of the neuropeptide [His(7)]-corazonin by immunocytochemical and mass spectrometric methods. It was concluded that this peptide is definitely present in a limited number of neurosecretory cells in the pars lateralis as well as in the corpora cardiaca (CC). Injection of either synthetic [His(7)]-corazonin or of extracts of CC of the normal coloured phenotype of S. gregaria failed to induce darkening of the cuticle, while albino Locusta migratoria, used as a positive control, turned dark. The conclusion is that the cause of albinism in the new S. gregaria albino is probably due to a defect in the receptor system for [His(7)]-corazonin or in the biosynthetic pathway of melanin.
