Age‐dependent response of adults of a homochrome grasshopper, Oedipoda miniata, to the dark‐colour‐inducing neurohormone (DCIN) of locusts
TLDR
The response to DCIN decreases from nymphs to young adults and it is further decreasing with ageing of the adults, suggesting that this species shows homochromy, but neither green‐brown, nor phase‐dependent colour polymorphism.
Hormonal Control of Body-Color Polyphenism in the American Grasshopper, Schistocerca americana: A Function of [His7]-Corazonin
TLDR
The results may suggest that [His7]-corazonin and JH are involved in the control of black pattern expression and green-brown polyphenism, respectively, in this grasshopper.
The dark‐colour‐inducing neurohormone of locusts: strain‐dependent and phase‐independent effects on adults of the migratory locust, Locusta migratoria
TLDR
It is demonstrated that the differential darkening response of the Okinawa albinos is caused not by albinism, but by the geographical origin (Okinawa) of the strain, the first report of geographical‐strain‐dependent differences in the response of an insect to a neurohormone.
Phenotypic plasticity in color without molt in adult grasshoppers of the genus Sphingonotus (Acrididae: Oedipodinae)
TLDR
The ability of these grasshoppers to produce different melanins in response to the environment supports a previous suggestion that they might be useful in the future development of animal models to study melanin-related diseases like melanoma and Parkinson ́s disease.
In vivo structure-activity studies on the dark-color-inducing neurohormone of locusts.
TLDR
It is indicated that the whole sequence of the DCIN is necessary to induce maximum darkening effect, and the -Ser-Xxx-Gly-Trp- partial sequence does not seem to be stabilized by a type II beta-turn, Nevertheless, existence of another kind of turn that includes this partial sequence is feasible.
Corazonin and locust phase polyphenism
TLDR
Transplantation of the brain and corpora cardiaca from various donors to albino locusts indicates the presence of corazonin or Corazonin-like substances in all 18 insect orders so far screened except for the Coleoptera.

Identification of the gregarization-associated dark-pigmentotropin in locusts through an albino mutant.
TLDR
Results show that even in isolated (solitary) nymphs, [His7] corazonin induces gregarious black patterns, and its primary structure shows some similarity with the vertebrate melanophore stimulating hormone.
Hormonal Deficiency Causing Albinism in Locusta migratoria
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.
