Researchers identified [Arg(7)] corazonin, a neuropeptide, from silkworms and crickets. This peptide induces dark coloration in albino locusts, proving useful for bioassays.

Area of Science:

  • Insect neuroendocrinology
  • Peptide hormone research
  • Comparative physiology

Background:

  • Neuropeptides regulate various physiological processes in insects.
  • The pigmentary system is crucial for insect adaptation and survival.
  • Previous studies indicated the presence of pigment-inducing neuropeptides in insects.

Purpose of the Study:

  • To isolate and identify neuropeptides responsible for dark coloration in Locusta migratoria.
  • To determine the effects of these identified neuropeptides on other insect species.
  • To establish a bioassay system for pigment-inducing neuropeptides.

Main Methods:

  • Isolation and purification of neuropeptides from Bombyx mori and Gryllus bimaculatus.
  • Amino acid sequencing to identify the isolated peptides.

  • Administration of identified peptides to albino Locusta migratoria nymphs to assess color change.
  • Testing the effects of the peptide on Bombyx mori and Gryllus bimaculatus.

    • Main Results:

    • Identical neuropeptides, [Arg(7)] corazonin, were isolated from silkworms and crickets.
    • [Arg(7)] corazonin induced dark coloration in albino Locusta migratoria nymphs at fmol to pmol levels.
    • High doses of the peptide did not affect body color or metamorphosis in silkworms or crickets.
    • The physiological roles of [Arg(7)] corazonin in silkworms and crickets remain undetermined.

    Conclusions:

    • The albino strain of Locusta migratoria serves as a specific and sensitive bioassay for [Arg(7)] corazonin.
    • [Arg(7)] corazonin is a potent inducer of melanization in locusts.
    • The function of [Arg(7)] corazonin may be species-specific, with its role in silkworms and crickets requiring further investigation.
