. Behavioural studies show that fullness of the hindgut influences the size of meals taken by fifth‐instar Locusta migratoria L. nymphs, with the relevant information coming from the ileum and passing via the terminal abdominal ganglion. Morphological and electrophysiological studies suggest that stretch receptors on the posterior ileum, associated with branches of the rectal nerves, register extension of the ileal fold and probably also an increase in ileal volume. A system in which the volumetric feedbacks from both the crop and hindgut interact in the regulation of meal size is postulated.
