Integrating information from several sensory cues to make optimal foraging decisions is crucial for all animals. Previously we found that Drosophila larvae switch their odor response from aversion to attraction when food-deprived. We now investigate how the larval behavior towards an aversive olfactory cue is modified by pre-exposure to different food components, such as carbohydrates and proteins. In addition, we also analyze how food deprivation and food component exposure affect locomotion behavior in Drosophila larvae. We find that only exposure to nutritious, protein-rich, food is sufficient to retain a fed olfactory response, however, it is not sufficient to display fed locomotion behavior. Thus, olfactory responses and locomotion behavior are regulated independently during food deprivation.
