Summary

During the development ofBombyx mori (monovoltin race) ecdysteroid levels were determined in oocytes, eggs, and haemolymph of larvae, and in the haemolymph of pupae. In haemolymph, the only RIA reactive materials are ecdysone and ecdysterone. In oocytes and eggs, other ecdysteroids are also detected. During larval instars, the ecdysteroid levels are low whereas they are very high during morphogenetic periods. During embryonic diapause, the ecdysone titer decreases during the cessation of morphogenesis.
