摘要：
Eggs of Locusta migratoria contain remarkably high concentrations of ecdysone and several other ecdysteroids. During the time-span of embryonic development (11 days) 4 distinct peaks of ecdysone concentration (up to 8 μM) are observed in the egg, demonstrating the ecdysiosynthetic capacity of the embryo. Only during postblastokinetic development, is ecdysone efficiently hydroxylated to 20-hydroxyachieved through conjugation. On the basis of optical and electron microscopic observations, we have been able to correlate precisely each of the four peaks of ecdysone concentration in the egg with the time of deposition of a cuticle by the embryonic tissues (peak 1: serosal cuticle; peak 2: first embryonic cuticle; peak 3: second embryonic cuticle; peak 4: third embryonic cuticle). © 1979.
