Gonadotropic effects of dopamine in isolated workers of the primitively eusocial wasp, Polistes chinensis
TLDR
Ovarian development was accelerated in dopamine-fed workers as compared to control workers of the same age fed only sucrose solution, indicating that dopamine plays a gonadotropic role in isolated workers in the primitively eusocial wasp, similar to the gonadotrop role previously reported for juvenile hormone.
Dopamine production in the brain is associated with caste-specific morphology and behavior in an artificial intermediate honey bee caste
TLDR
Dopamine production in the brain is associated with the continuous caste-specific morphology, as well as being linked to the amount of tyrosine taken from food, and it supports the aggressive behavior of queen-type females.
Biogenic amines shift during the pre-reproductive to reproductive transition in the small carpenter bee, Ceratina calcarata
TLDR
It is 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, the first characterization of biogenic amines in the brains of males.
Bumble bee queens activate dopamine production and gene expression in nutritional signaling pathways in the brain
To explore the neuroendocrine mechanisms underlying caste-specific behavior and its evolution from primitive to advanced eusocial bees, the monoamine levels and expression of genes involved in

Social Evolution With Decoupling of Multiple Roles of Biogenic Amines Into Different Phenotypes in Hymenoptera
TLDR
Recent progress in the understanding of the neurohormonal regulation of reproduction and social behavior in eusocial hymenopterans is reviewed, with an emphasis on biogenic amines.
Changes in the levels of biogenic amines associated with aggressive behavior of queen in the social parasite ant Vollenhovia nipponica
TLDR
In V. nipponica queens, 5-HT and DA could regulate motivation of aggression, irrespective of age, however, the changes of biogenic amines are possibly affected by other behavioral factors.

Brain biogenic amines and reproductive dominance in bumble bees (Bombus terrestris)
TLDR
Brain levels of dopamine, serotonin, and octopamine were measured in bumble bee workers and queens that differ in behavioral and reproductive state to suggest the role of biogenic amines in reproductive division of labor in social insects.
Changes in brain amine levels associated with the morphological and behavioural development of the worker honeybee
TLDR
Results suggest that an age-dependent change in amine levels occurs in the brain of the worker bee, and significant differences inAmine levels in the optic lobes of nectar foragers and pollen foragers indicate that some differences in Amine levels occur independent of worker age.
Depression of brain dopamine and its metabolite after mating in European honeybee (Apis mellifera) queens
TLDR
It is speculated that higher amounts of brain dopamine in virgin queens might be involved in activation of ovarian follicles arrested in previtellogenic stages, as well as regulation of their characteristic behaviors.
Juvenile hormone, reproduction, and worker behavior in the neotropical social wasp Polistes canadensis.
TLDR
Experimental application of the JH analog methoprene accelerates the onset of guarding behavior, an age-correlated task, and increases the number of foraging females, and these findings support a view of social insect evolution that sees the contrasting worker and queen phenotypes as derived via decoupling of reproductive and brood-care components of the ancestral solitary reproductive physiology.
Effects of Population Density on Growth, Behavior and Levels of Biogenic Amines in the Cricket, Gryllus bimaculatus
TLDR
The results indicate that high population density affects aminergic systems which in turn modulate various biological events, such as development, growth and behavior in the cricket Gryllus bimaculatus.
Age-related changes in biogenic amines in individual brains of the ant Pheidole dentata
TLDR
Serotonin and dopamine levels were significantly correlated with worker age: both increased as minor workers matured, and serotonin rose significantly in the oldest ants, suggesting an involvement of neuromodulators in minor worker behavioral ontogeny and temporal polyethism in P. dentata.
