Abstract
PREVENTION of hyperphagia by some mechanism is essential to feeding animals. To date relatively few such control mechanisms have been studied in detail. Termination of feeding by internal inhibitory feedback from stretch receptors is documented for Phormia regina1, Locusta migratoria2, Chortoicetes terminifera3 and Aplysia californica4. Chemosensory adaptation has been suggested for Phormia1 and Chortoicetes3, and in Locusta activation of foregut stretch receptors will, through a nervous and hormonal pathway, close the terminal pores of chemosensory sensilla on the maxillary palps5. We present here evidence showing that stimulation of a pair of oesophageal contact chemoreceptor organs can slow the ingestion rate and terminate feeding in Homarus gammarus.
