Attempted Extraction of Crustacean Moulting Hormone from Isolated Y-Organs

Nature volume 185, pages 543–544 (1960)Cite this article

Abstract

ECHALIER1,2 has shown, by extirpation and implantation experiments, that the Y-organs of Crustacea3 produce the moulting hormone. The Y-organs are therefore physiologically (and morphologically) homologous to the prothoracic glands of insects. It has also been demonstrated4,5 that extracts from whole Crustaea (Crangon vulgaris 6, Emerita talpodia, Libinia spp.7) are active in insects, initiating puparium formation in ligated Calliphora larvæ. Thus, they have the same action as ecdysone, the moulting hormone or prothoracic gland hormone of insects.
