TLDR
It is shown that the age-related transition by honey bees from hive work to foraging is associated with an increase in the expression of the foraging (for) gene, which encodes a guanosine 3′,5′-monophosphate (cGMP)–dependent protein kinase (PKG).Abstract:
Genes can affect natural behavioral variation in different ways. Allelic variation causes alternative behavioral phenotypes, whereas changes in gene expression can influence the initiation of behavior at different ages. We show that the age-related transition by honey bees from hive work to foraging is associated with an increase in the expression of the foraging (for) gene, which encodes a guanosine 3',5'-monophosphate (cGMP)-dependent protein kinase (PKG). cGMP treatment elevated PKG activity and caused foraging behavior. Previous research showed that allelic differences in PKG expression result in two Drosophila foraging variants. The same gene can thus exert different types of influence on a behavior.read more

Gene expression profiles in the brain predict behavior in individual honey bees
TL;DR: It is shown that the age-related transition by adult honey bees from hive work to foraging is associated with changes in messenger RNA abundance in the brain for 39% of genes tested, demonstrating more extensive genomic plasticity in the adult brain than has yet been shown.

Meeting the energetic demands of insect diapause: nutrient storage and utilization.
TL;DR: It is provided evidence that interactions between nutrient storage and metabolism can influence the decision to enter diapause and determine how long to remain in diAPause, and several mechanisms that have the potential to contribute to Diapause-associated nutrient homeostasis are proposed.

Genes and Social Behavior
TL;DR: Progress has been made in identifying and understanding two key “vectors of influence” that link genes, the brain, and social behavior: social information alters gene expression in the brain to influence behavior, and genetic variation influences brain function and socialbehavior.
Journal ArticleDOI
The gene vitellogenin has multiple coordinating effects on social organization.
TL;DR: It is shown by use of RNA interference that vitellogenin gene activity paces onset of foraging behavior, primes bees for specialized foraging tasks, and influences worker longevity, supporting the view that the worker specializations that characterize hymenopteran sociality evolved through co-option of reproductive regulatory pathways.

TL;DR: Findings derived from an eclectic mix of species that show varying levels of sociality provide the foundation for the integration of molecular biology, genomics, neuroscience, behavioural biology and evolutionary biology that is necessary for this endeavour.

TL;DR: In this paper, the foraging gene (for), a gene that has two naturally occurring variants in Drosophila melanogaster food-search behavior: rover and sitter, was placed for mutations in the dg2 gene, which encodes a cyclic guanosine monophosphate (cGMP)-dependent protein kinase (PKG).

Cellular mechanisms of social attachment.
TL;DR: It is hypothesize that oxytocin and vasopressin may be facilitating affiliation and social attachment in monogamous species by modulating these reward pathways.

What Do the Mushroom Bodies Do for the Insect Brain? An Introduction
TL;DR: In humans and other primates, lesions and noninvasive imaging techniques have provided fascinating insights into the underlying functional topology of the brain, but these approaches reveal structure–function relationships that are difficult to interpret in terms of network-based brain models.

Identification of a major gene regulating complex social behavior.
TL;DR: It is shown that single genes of major effect can underlie the expression of complex behaviors important in social evolution, and regulation of social organization by Gp-9 is conserved in South American fire ant species exhibiting social polymorphism.

TL;DR: 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.
