The central role of the haemolymph in the regulation of nutrient intake in insects


Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS.


Abstract. A synthesis is presented for the control of nutrient intake in insects. The haemolymph plays a central role and provides a constantly updated summary of nutritional state. Various ways are discussed in which haemolymph parameters are directly and indirectly linked to the three key aspects of feeding behaviour: food location, food selection and ingestion.
