## 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
Carbonic anhydrase (CAI activity was assayed by a histochemical method in mounted cryostat sections of larval midgut of Munducu sextu (Insecta: Sphingidae). In anterior and middle midgut most CA activity was associated with apical microvilli of goblet cells; with occasional patchy staining of the co
