Researchers say hormones are key to evolution of insect metamorphosis
... hormones,juvenile hormones (JH) and ecdysteroids, interact during embryonic, larval andpupal stages, the researchers said. Juvenile hormones suppress the development of adult structures. In insects withpartial or no metamorphosis, the absence of JH during embryo formation anddevelopment allows the embryo to ......propagated and dissipated and theway in which they interact with the bottom, currents and otherwaves.
