Juvenile Retrospect and in Prospect

  • C. M. Williams


Figure 1 reproduces a summary of endocrine dynamics which, I venture to think, identifies most of the phenomena that will be dealt with in this Symposium. For present purposes, let the endocrine gland be the corpora allata (CA) and the endocrine agent be juvenile hormone (JH). Attention is directed to the “controlling mechanisms” modulating in this case the synthesis and secretion of JH by the CA. Since JH has never been shown to accumulate in the glands themselves, the indications are that CA activity is adjusted by the modulation of synthesis rather than secretion (Tobe and Pratt, 1974).
