Dopamine is an important catecholamine neurotransmitter in invertebrates and vertebrates.
It is biochemically derived from tyrosine via L-DOPA. It is most abundant in the central …

The biogenic monoamine octopamine (OA) is a crucial regulator of invertebrate physiology
and behavior. Since its discovery in the 1950s in octopus salivary glands, OA has been …

Convergent evolution of eusociality with the division of reproduction and its plastic transition
in Hymenoptera has long attracted the attention of researchers. To explain the evolutionary …

Octopamine (OA) and tyramine (TA) are phenolamines that are synthesised from tyrosine
and are widely distributed in insects. These amines play vital roles as neurotransmitters …

Dominance rank in animal societies is correlated with changes in both reproductive
physiology and behavior. In some social insects, dominance status is used to determine a …

Caste polymorphism in eusocial insects is based on morphological plasticity and linked to
physiological and behavioral characteristics. To test the possibility that dopamine production …

The transition to social living, combined with the ability of individuals within a society to
communicate and cooperate on common tasks, represents one of the greatest levels of …

We aimed to investigate the roles of dopamine in regulating caste-specific behaviors in
bumble bees and mating-related behaviors in bumble bee gynes. We examined caste …

Queen and worker honeybees differ profoundly in reproductive capacity. The queen of this
complex society, with 200 highly active ovarioles in each ovary, is the fertile caste, whereas …

Simple Summary In this review, we describe sex-specific differences in the regulatory
systems for dopamine production in the brains of social insects, focusing on the honey bee …
