Honey bee colonies typically consist of about 20–40 thousand workers, zero to few
thousand males (drones), depending on the time of year, and a single queen, the mother of …

Publisher Summary This chapter reviews the evidence for endocrine influences on division
of labor in insect societies. Juvenile hormone (JH) has been studied most extensively. The …

The familiar European hive bee, Apis mellifera, has long dominated honey bee research.
But in the last 15 years, teams in China, Japan, Malaysia, and Thailand began to shift focus …

Previous research showed that the presence of older workers causes a delayed onset of
foraging in younger individuals in honey bee colonies, but a specific worker inhibitory factor …

Honey bees undergo an age-related, socially regulated transition from working in the hive to
foraging that has been previously associated with changes in the expression of thousands of …

Publisher Summary This chapter discusses the endocrine control of insect polyphenism.
Polyphenism in insects is associated with some of the most striking and successful life …

Previous studies of the division of labor in colonies of eusocial Hymenoptera (wasps and
bees) have led to two hypotheses regarding the evolution of juvenile hormone (JH) …

The switch from within-hive activities to foraging behavior is a major transition in the life
cycle of a honeybee (Apis mellifera) worker. A prominent regulatory role in this switch has …

One approach to understanding proximate and evolutionary mechanisms of social behavior
is to analyze mechanisms of neural and behavioral plasticity and their underlying genes …

Young adult honey bees work inside the beehive “nursing” brood around the clock with no
circadian rhythms; older bees forage for nectar and pollen outside with strong circadian …
