Summary Proctodaea of European corn borer (Ostrinia nubilalis) and gypsy moth (Lymantria dispar) last instars (larvae) contain prothoracicotropic factors that stimulate the prothoracic glands (PGs) of the gypsy moth to produce both ecdysone and 3-dehydroecdysone (precursors to the insect molting hormone) in a dose-dependent manner. In a separate in vivo assay, injections of proctodaeal extracts into gypsy moth larvae that were head-ligated before the release of the molt-stimulating brain hormone, PTTH, resulted in a pupal molt.
