The larval-pupal transformation of Manduca sexta results from an exposure to ecdysteroids
in the absence of juvenile hormone (the commitment pulse), followed by a larger exposure …

The enteric plexus is a discrete portion of the enteric nervous system (ENS) in the larval
moth Manduca sexta. It consists of a stereotyped array of nerves extending across specific …

The nervous system of an adult moth is comprised of retained larval neurons that are
remodeled during metamorphosis and a set of new adult specific neurons. The new neurons …

With antisera to gastrin/cholecystokinin, we studied the postembryonic development of
neurons in the thoracic ganglia of the blowfly Calliphora erythrocephala. There are some …

The ecdysteroid dependence of developmental events during the larval-pupal
transformation of the tobacco hornworm, Manduca sexta, was studied using the technique of …

Each of the unfused abdominal ganglia in the larval, pupal, and adult stages of the
hawkmoth, Manduca sexta, has two large ventral median neurons with axons that bifurcate …

The abdominal prolegs of Manduca sexta larvae are eliminated at the onset of
metamorphosis. Previous work showed that the prepupal peak of ecdysteroids in the …

During insect metamorphosis, the nervous system must be reorganized to allow the
production of unique behaviors during each life stage. In the hawkmoth, Manduca sexta, it …

A decline in circulating 20‐hydroxyecdysone permits the emergence of the adult Manduca
sexta moth; this endocrine signal also triggers the death of approximately half of the neurons …

Insect metamorphosis is controlled by a small ensemble of developmental hormones
including a class of steroids—the ecdysteroids. In the tobacco hornworm, Manduca sexta …
