Studies on the role of juvenile hormone (JH) in adult social Hymenoptera have focused on the regulation of two fundamental aspects of colony organization: reproductive division of labor between queens and workers and age-related division of labor among workers. JH acts as a gonadotropin in the primitively eusocial wasp and bumble bee species studied, and may also play this role in the advanced eusocial fire ants. However, there is no evidence that JH acts as a traditional gonadotropin in the… Expand
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. Expand
Exploring the role of juvenile hormone and vitellogenin in reproduction and social behavior in bumble bees
TLDR
It is suggested that social interactions affect vg levels more strongly than a worker’s reproductive physiological state, and that juvenile hormone and vg are uncoupled in this species. Expand
Juvenile hormone manipulation affects female reproductive status and aggressiveness in a non-social parasitoid wasp.
TLDR
This is the first study showing that hormone manipulation can modulate females' reproduction status and behavior during intraspecific competition over hosts in a non-social hymenopteran parasitoid, and highlights how JH affects egg maturation and aggressive behaviors in Eupelmus vuilleti females. Expand
Gonadotropic and Physiological Functions of Juvenile Hormone in Bumblebee (Bombus terrestris) Workers
TLDR
Allatectomy and replacement therapies performed to manipulate JH levels in workers of the "primitively eusocial" bumblebee Bombus terrestris provide a strong support for the hypothesis that in contrast to honey bees, JH is a gonadotropin in bumblebees and lend credence to the hypotheses that the evolution of advanced eussociality in honey bees was associated with major modifications in JH signaling. Expand
The effect of juvenile hormone on temporal polyethism in the paper wasp Polistes dominulus
TLDR
First, it is shown that workers in P. dominulus have an age-related division of labor, as workers switch from nest work to foraging as they mature, and application of JH accelerates the onset of foraging behavior. Expand
Juvenile hormone levels reflect social opportunities in the facultatively eusocial sweat bee Megalopta genalis (Hymenoptera: Halictidae)
TLDR
The first evidence for a link between endocrine processes and social behavior in a facultatively eusocial bee, Megalopta genalis (Halictidae), is reported, supporting the hypothesis that endocrine modifications are involved in the evolutionary decoupling of reproductive and somatic effort in social insects. Expand
Juvenile hormone regulates brain-reproduction tradeoff in bumble bees but not in honey bees
TLDR
The results suggest that the evolution of complex eusociality in honey bees was associated with modifications in hormonal signalling supporting extended and extremely high fertility while reducing the ancient costs of high gonadotropin titers to the brain. Expand

TLDR
Study of subsocial insects suggests that when JH is non-gonadotropic, the specific associations of high JH, low vitellogenin, suppressed ovarian development and elevated metabolism may parallel those in workers of eusocial insects. Expand
Precocene-I inhibits juvenile hormone biosynthesis, ovarian activation, aggression and alters sterility signal production in bumble bee (Bombus terrestris) workers
TLDR
The ability to chemically reduce JH titer provides a non-intrusive method to probe the evolutionary changes associated with JH and the hormonal mechanisms that are associated with reproduction and behavior in social insects. Expand
Regulation of reproductive plasticity in the ant Harpegnathos saltator
TLDR
The results suggest that caste determination originally occurred late in the larval stage in the ancestral condition but has shifted earlier in development in species that began to acquire advanced characteristics, including queen-worker dimorphism as well as multiple worker castes. Expand

Juvenile hormone, behavioral maturation, and brain structure in the honey bee.
TLDR
It is proposed that juvenile hormone may mediate neural plasticity in the brains of adult honey bees to support the demanding cognitive task of foraging. Expand
Effects of experience and juvenile hormone on the organization of the mushroom bodies of honey bees.
TLDR
Analysis of the big back bees demonstrates that certain aspects of adult brain plasticity associated with foraging can be displayed by worker bees treated with methoprene independent of foraging experience, and suggests a potentially important role of visual stimulation, possibly interacting with juvenile hormone, as an organizer of the mushroom bodies.

TLDR
This work used two experimental paradigms inspired by developmental biology to study how bees obtain information on changing colony needs that results in precocious foraging and found similarities in the integration of activity that exist between individuals in insect colonies and cells in metazoans. Expand
Regulation of Reproduction in Eusocial Hymenoptera
TLDR
An evolutionary framework focuses attention on the social factors that regulate reproduction, but to avoid separating them artificially from their ecological context, factors extrinsic to a colony must occasionally enter the discussion. Expand
Comparison of juvenile hormone and ecdysteroid haemolymph titres in adult worker and queen honey bees (Apis mellifera)
TLDR
Comparison of juvenile hormone and edcysteroid titres suggests that ecdysteroids are not involved in the regulation of age polyethism but may play a role in theregulation of reproduction in honey bees. Expand
Juvenile hormone does not affect division of labor in bumble bee colonies (Hymenoptera: Apidae).
TLDR
Because bumble bees do not exhibit strong age polyethism, these results are consistent with findings in honey bees that JH influences only the performance of age-dependent tasks. Expand
Regulation of honey bee division of labor by colony age demography
TLDR
Results demonstrate that plasticity in age-related division of labor in honey bee colonies is at least partially controlled by social factors, suggesting that colony age demography directly influences temporal division of Labor. Expand
Hormonal regulation of behavioural development in the honey bee is based on changes in the rate of juvenile hormone biosynthesis
TLDR
It is demonstrated that differences in juvenile hormone titres among bees performing different age-dependent tasks are a consequence of changes in rates of hormone synthesis by the corpora allata, and that the radiochemical assay will be useful in further studies of hormonal regulation of bee behaviour.

Developmental and Physiological Determinants of Caste in Social Hymenoptera: Evolutionary Implications
TLDR
A developmental view of the evolution of societies is presented and two complementary questions are raised regarding the relationship between social structure and the factors that determine physical or physiological differences among females are raised. Expand
Reproduction in worker honey bees is associated with low juvenile hormone titers and rates of biosynthesis.
TLDR
Ovary development was inhibited slightly by application of the JH analog methoprene to 1-day-old bees, but was not affected by application to older bees, at least some already displaying egg-laying behavior. Expand
