Title
Identification of the gregarization-associated dark-pigmentotropin in locusts through an albino mutant
Author
Abstract
In response to crowding, locusts develop characteristic black patterns that are well discernible in the gregarious phase at outbreaks. We report here a dark-color-inducing neuropeptide (dark-pigmentotropin) from the corpora cardiaca of two plague locusts, Schistocerca gregaria and Locusta migratoria, The chromatographic isolation of this neuropeptide,vas monitored by using a bioassay with an albino mutant of L. migratoria. The neurohormone, consisting of 11 amino acids, is identical to [His(7)] corazonin, previously isolated front corpora cardiaca of another acridid without known function. The present results show that even in isolated (solitary) nymphs, [His(7)] corazonin induces gregarious black patterns, Its primary structure shows some similarity with the vertebrate melanophore stimulating hormone.
