**Abstract**

Several biogenic amines neurotransmitters are involved in various social behaviors, including olfaction learning behavior, cast differentiation, generation overlapping and sociability in honeybees. One of the brain's primary functions is remembering and learning the information related to food and odor. Dopamine (DA) is an important signaling molecule derived from the amino acid tyrosine. It is also known as a key neurohormone, neuromodulator and neurotransmitter in vertebrates as well as invertebrates and several studies indicated their important role in olfaction success, rewarding prediction, learning, memory, motor functions, sleep and arousal, aggression, and numerous other behaviors. Evidence suggests that DA plays several roles in honeybees, especially in olfaction success. Three DA receptors, AmDOP1, AmDOP2 and AmDOP3, have been characterized and clones. In this chapter, I focus on the regulation and involvement of the DA in olfactory learning behavior, locomotor function, motivation, and happy memories. This chapter represents an attempt to associate the role of dopamine receptors in olfaction success in honeybees.
