Abstract
The tubular peritrophic membranes of Calliphora are formed by the secreting cells of the proventriculus at a rate of 3.5 ± 1 mm per hour. It has been estimated that each of these cells produces its own weight in membrane material in about one day. Autoradiography of peritrophic membranes from flies injected with glucose-C 14 show cross bands as well as longitudinal bands, indicating a periodic incorporation of radioactive material and therefore a different chemical composition, which may be of importance for transport phenomena.
