Abstract The recent report of an ecdysis-triggering hormone (ETH) in the tobacco hornworm Manduca sexta and several other Lepidoptera prompted the search for the homologous hormone in the pest noctuid, Helicoverpa armigera. In M. sexta, ETH is produced in a large cell that forms part of a three-cell epitracheal gland complex found near each of the the larval and pupal spiracles. The homologous glands were found in H. armigera and an ecdysis-triggering function of the gland contents was confirmed by the induction of premature ecdysis after injection of a crude gland extract into pupae.
