Midgut Epithelial Regeneration as a Means of Studying Insect Digestion

Abstract

The small size of insects does not permit the study of their digestive processes by the classical methods of mammalian physiology; the production of fistulæ, the study of changes in blood constituents, and the effects of nervous stimulation, for example, have not been successfully exploited with insects. Advances have, in fact, been almost entirely dependent upon the applications of normal histological techniques, and these are inadequate for many purposes.
