## Abstract Enzyme activities and mitochondrial substrate oxidation were measured in the posterior midguts of tobacco hornworms at different larval stages. A comparison of third, fourth, and fifth instars demonstrated no differences in citrate synthase activity (per gram of midgut), indicating that
During the last larval instar of Manduca sexta (tobacco hornworm), the insect enters the wandering phase, in which the animal ceases feeding and the structural reorganization of the midgut begins. Midgut metabolism and ion transport in midguts of feeding and wandering (day 5) fifth-instar tobacco ho
