The hypothesis that [His7]-corazonin plays an important role in the control of phase polymorphism in locusts is supported, thanks to single injections of the peptide into individually-reared nymphs at different instars.
The dark-color inducing neuropeptide, [His(7)]-corazonin, causes a shift in morphometic characteristics towards the gregarious phase in isolated-reared (solitarious) Locusta migratoria.

Effects of temperature and [His7]‐corazonin on the body darkening in Locusta migratoria

It is indicated that high temperature may induce light body coloration by suppressing the release of [His7]‐corazonin in normal locusts.

The results suggest that [His7]-corazonin or a similar neuropeptide may be involved in the control of body color in the locusts and grasshoppers, but not in the katydid.
Body color polymorphism in nymphs and adults of a katydid, Conocephalus maculatus (Orthoptera: Tettigoniidae)

The present results show that color-morph determination is controlled mainly by genetic factors and little affected by environmental factors in nymphs and adults of C. maculatus.

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.

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.

Examining the hypothesis of Potgieter in the light of these experiments, it is found that the data presented in Tables XXI to XXIV are in direct contradiction with the three phases enumerated above.
