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 was monitored by using a bioassay with an albino mutant of L. migratoria. The neurohormone, consisting of 11 amino acids, is identical to [His7…

The dark‐colour‐inducing neurohormone of locusts in relation to an albino mutant of Schistocerca gregaria
In the albino mutant of an Okinawa strain of Locusta migratoria (L.) (Orthoptera: Acrididae), albinism is caused by the absence of the dark‐colour‐inducing neurohormone (DCIN), which is present in
Genetic and hormonal control of melanization in reddish–brown and albino mutants in the desert locust Schistocerca gregaria
TLDR
The results suggest the possibility that the RB mutant gene regulates the intensity of melanization, possibly through controlling the pathway of pigment biosynthesis associated with [His7]‐corazonin.
Mass spectrometric evidence for the deficiency in the dark-color-inducing hormone,.
TLDR
Using nanoflow-liquid chromatography-mass spectrometry, it is demonstrated that this dark colour-inducing hormone is, however, present in the corpora cardiaca of solitary locusts (Schistocerca gregaria).
A reddish-brown mutant in the desert locust, Schistocerca gregaria: phase-dependent expression and genetic control
TLDR
Results suggest that the expression of the RB phenotype is phase-dependent and the RB gene might regulate the intensity of melanization in this reddish-brown mutant of the desert locust.

TLDR
Implantation of corpora cardiaca taken from a normal hopper caused albino hoppers to turn grey, reddish, brown, or dark brown like the colors of normal isolated solitary individuals, and others to develop the black and orange coloration like that of normal gregarious hoppers, suggesting that some hormonal factor(s) commonly present in different insects can promote dark pigmentation inAlbino locusts.

TLDR
The structure of the predicted preprocorazonin is remarkably similar to the preprohormone of adipokinetics hormone, which suggests that corazonin and adipokinetic hormone have a common evolutionary origin.
