title: [Variations in the level of ecdysones during the intermolt of male Orchestia gammarella Pallas (Crustacea. amphipoda) by radioimmunoassay].
abstract: The molting hormone content is low during stages C, D0, D1' a-b; it rises up in D 1' c and attains a maximum in D 2. An important decrease of the hormone titer is observed at ecdysis. This titer is slightly lower at stage A and increases again at stage B. Only ecdysterone is detected at stages B and D 2.
