This study shows that food perception alone, through olfactory signaling and serotonin receptors, stimulates oviposition in Drosophila without requiring nutrient intake.

This study shows that insulin receptor signaling in sweet gustatory receptor neurons of Drosophila modulates sugar taste sensitivity and feeding behavior based on metabolic state.

This study shows artificial sweeteners activate both sweet and bitter taste neurons in Drosophila, with varying behavioral effects depending on concentration and compound type.
