Central to the theme of my research is the idea that feeding behaviour is intrinsically linked with metabolism. Metabolism incurs an energetic cost which can be met for short periods of time through the catabolism of internal energy stores contained in muscle and fat body tissues. However, over longer periods of time these internal energy stores must be replenished so that metabolic homeostasis can be restored. To this end, feeding behaviour is modified in response to changes in metabolism, such that a hungry fly will search for and ingest food. My thesis work aims to characterize a role for the foraging gene in the corpora cardiaca (CC) as a regulator of larval and adult feeding-related behaviour. Through the examination of changes in physiological and molecular characters resulting from the manipulation of foraging in the CC, this work has implicated the foraging gene as a key player in the regulation of metabolic homeostasis in Drosophila melanogaster.
