ABSTRACT 20-Hydroxyecdysone (20-HE) stimulated the initiation of premolt (apolysis) in third and fourth instar Rhithropanopeus harrisii larvae in vivo and in spines explanted from third and fourth instar larvae in vitro. The premolt-initiating activity of 20-HE, in vitro, was inhibited by extracts of third or fourth instar zocae, megalopae, and shrimp eyestalks. The results suggest that apolysis in crab larvae may be controlled by both 20-HE and MIH.
