Abstract
1. The effect of molt cycle stage and beta-ecdysone on protein synthesis in the horsehoe crab, Limulus polyphemus, was examined. 2. A pronounced decline in protein specific radioactivity after incubation with 14C-leucine was noted in muscle, midgut gland and operculum from postmolt to intermolt to premolt and in gut and gill tissue from intermolt to premolt. 3. beta-Ecdysone injections produced an early stimulation of protein synthesis in the midgut gland followed by strong inhibition within 48 hr. 4. Results are compared with those obtained in mandibulate arthropods.
