Abstract: | Summary Corpora allata of the cockroachDiploptera punctata normally synthesize only the isoprenoid juvenile hormone III (JH III). Only under extreme in vitro conditions (absence of carbon sources other than propionate) do they produce trace amounts of the homoisoprenoid JH II in addition to JH III. The specificity of the in vitro synthesis of JH III byD. punctata is thus consistent with the observed lack of homoisoprenoid JHs in this insect. |
