Serotonin (5‐hydroxytryptamine, 5‐HT) is an important biogenic amine in insects, which regulates and controls many important physiological and behavioral processes by binding to different G protein‐coupled receptors. The physiological functions of 5‐HT and its receptors in olfactory learning and memory, courtship, and mating behaviors, have been reported in the model insect Drosophila melanogaster. However, little is known about the molecular properties, pharmacological characterization, and physiological functions of 5‐HT receptors in the important agricultural pest Helicoverpa armigera.
