Abstract
Juvenile Hormone, Biosynthesis, Cecropia Moth Adult 3-4 day old males of the giant silk moth H yalophora cecropia incorporate the label of [1-14C] propionate and [1-14C]butyrate in JH-I and JH-II. [1-14C]propionate is used for the bio synthesis of the hormones as an intact C3-unit. Three possible intermediates in the biosynthesis of JH-I-(E,E,Z)-7-ethyl-3,11-dimethyl-2,6,10-tridecatrienoic acid, its methyl ester, and the cor responding alcohol - were converted in low yields to the hormone. Methyl 7-ethyl-3,11-dimethyl-tridecanoate was not incorporated. Mevalonate applied to larvae before pupation was not used for the synthesis of a hypothetical JH-I precursor.
