Highlights•We review recent progress in studies on DoL in reproduction and task
performance in bumble bees.•DoL and social organization are plastic in bumble …

Juvenile hormone (JH) regulates developmental and physiological processes in insects. In
bumble bees, the hormone acts as a gonadotropin that mediates ovary development, but the …

Juvenile hormone (JH) is a modulator of many physiological transitions in insects, including
molting, metamorphosis, diapause, and reproduction. These processes often include …

Understanding the social evolution leading to insect eusociality requires, among other, a
detailed insight into endocrine regulatory mechanisms that have been co-opted from solitary …

Gonadotropic hormones coordinate processes in diverse tissues regulating animal
reproductive physiology and behavior. Juvenile hormone (JH) is the ancient and most …

Division of labor is one of the most striking features in the evolution of eusociality. Juvenile
hormone (JH) mediates reproductive status and aggression among nestmates in primitively …

Bumble bee queens initiate nests solitarily and transition to living socially once they
successfully rear their first cohort of offspring. Bumble bees are disproportionately important …

Juvenile hormone (JH) is a key regulator of insect development and reproduction. Given that
JH commonly affects adult insect fertility, it has been hypothesized to also regulate …

Simple Summary Behavioural specialisation of individuals may improve the performance of
groups, but could also limit the ability to switch tasks (behavioural 'plasticity') in response to …

Hormones are often major regulators of complex behaviors, such as mating and
reproduction. In insects, juvenile hormone (JH) is integral to many components of …
