Title: The effects of crustacean and locust ecdysons on moulting and proecdysis in juvenile shore crabs, Carcinus maenas
Abstract: Bilateral destruction of the Y-organ of immature shore crabs, Carcinus maenas, 10 to 16 mm in carapace breadth, resulted in a cessation of moulting. Injections of extracts derived from the same species, or from Mysis, Meganyctiphanes, the copepod Euchaeta, or the locust Schistocerca, led to renewed moulting. It is suggested that different arthropod groups possess differing ecdysons which are all, however, reciprocally active when injected in high enough dose. Evidence is presented that ecdyson affects the later stages of proecdysis and that it does not serve merely as a trigger for the initiation of this stage.
