“…In multiple species of moths, increased octopamine levels have been shown to improve pheromone discrimination and orientation (Dolzer et al 2001;Linn 1997). Similarly, increases in both dopamine and octopamine were associated with sexual maturation and the onset of mating flight behavior in honey bees (Mezawa et al 2013). We found that C. calcarata males produce an intermediate amount of both octopamine and serotonin compared to prereproductive and reproductive females ( Figure 2).…”

Biogenic amines shift during the pre-reproductive to reproductive transition in the small carpenter bee, Ceratina calcarata

The shift from solitary to social living is a major evolutionary transition for social insects. In bees, this transition is marked by certain females becoming reproductive and reducing their role in nest and offspring care, duties that are assumed by other females. Biogenic amines play a significant role in regulating these behaviors in both solitary and social insects. How has the function of biogenic amines in solitary insects been coopted for social behaviors? Here, we used Ceratina calcarata , a behaviorally well-studied small subsocial carpenter bee to explore how biogenic amines may play a role in the reproductive shift over a season. We found that as females transition from a pre-reproductive to reproductive state, ovarian development is accompanied by an increase in brain levels of octopamine and serotonin. For comparison, we provide the first characterization of biogenic amines in the brains of males. These results suggest the essential role of biogenic amines in the transition of reproductive states in a bee on the brink of sociality and provide a deeper understanding of how biogenic amines may have influenced the evolution of social behavior.biogenic amines / reproductive status / octopamine / serotonin / incipiently social Apidologie (2019) 50:90-99

“…In honey bee ( Apis mellifera ), queen pheromone have been shown to modulate dopamine signaling pathways in the worker bees [98]. Furthermore, in male honeybees, juvenile hormone (JH), which regulate development and reproduction, has been shown to increase the levels of dopamine in the brain [99, 100]. JH and brain dopamine levels have been shown to increase during sexual maturation, and topical application of a JH analog increases the level of dopamine in the brain of male honeybees [101, 102].…”

“…Collected individuals were immersed immediately in liquid nitrogen and stored therein using a storage container DR-3 (Cryo one, Osaka, Japan) until use. Within one month, measurements of DA and N -acetyldopamine (NADA, a metabolite of DA; electronic supplementary material, figure S2) levels in the brains were performed based on a previous study [ 30 ]. Frozen individuals were separated into heads and other body parts on ice, and brains were isolated from the heads in ice-cold saline (128.33 mM NaCl, 2.68 mM KCl, 1.80 mM CaCl 2 , pH 6.7) within 3 min.…”

Dopamine regulates termite soldier differentiation through trophallactic behaviours

et al. 2016

Caste polyphenism in social insects is regulated by social interactions among colony members. Trophallaxis is one of the most frequently observed interactions, but no studies have been conducted identifying the intrinsic factors involved in this behaviour and caste differentiation. Dopamine (DA) has multiple roles in the modulation of behaviours and physiology, and it produces species-specific behaviours in animals. Here, to verify the role of DA in termite soldier differentiation, we focused on the first soldier in an incipient colony of Zootermopsis nevadensis, which always differentiates from the oldest 3rd instar (No. 1 larva) via a presoldier. First, brain DA levels of the No. 1 larva at day 3 after its appearance were significantly higher than day 0. Second, DA synthesis gene expression levels were extraordinarily high in the No. 1 larva at day 0–1 after appearance. Finally, injection of a DA receptor antagonist into the No. 1 larva resulted in the inhibition of presoldier differentiation. Behavioural observations of the antagonist or control-injected larvae suggested that brain DA and signalling activity regulate the frequencies of trophallaxis from reproductives and presoldier differentiation. Because trophallaxis is a social behaviour frequently observed in natural conditions, the role of DA should be investigated in other social insects with frequent trophallactic and allogrooming behaviour.
