Heritable effects on caste determination and colony-level sex allocation in termites under field conditions [PDF]
iScience, 2023 Summary: The ecological success of social insects is attributed to the division of labor, where newly hatched offspring differentiate into either fertile progeny or functionally sterile worker castes.

Differential expression of some termite neuropeptides and insulin/IGF-related hormones and their plausible functions in growth, reproduction and caste determination [PDF]
PeerJ, 2023 Background Insulin-like growth factor (IGF) and other insulin-like peptides (ilps) are important hormones regulating growth and development in animals.

Trophic eggs affect caste determination in the ant Pogonomyrmex rugosus [PDF]
eLifeUnderstanding how a single genome creates distinct phenotypes remains a fundamental challenge for biologists. Social insects provide a striking example of polyphenism, with queen and worker castes exhibiting morphological, behavioral, and reproductive ...

MicroRNAs in Honey Bee Caste Determination. [PDF]
Sci Rep, 2016 AbstractThe cellular mechanisms employed by some organisms to produce contrasting morphological and reproductive phenotypes from the same genome remains one of the key unresolved issues in biology. Honeybees (Apis mellifera) use differential feeding and a haplodiploid sex determination system to generate three distinct organismal outcomes from the same

Brain physiology during photoperiod-related caste determination in the primitively eusocial wasp Polistes jokahamae [PDF]
Scientific ReportsAdult females of the primitively eusocial wasp Polistes jokahamae can change caste in response to photoperiod length. Short-day photoperiod females store more lipids but have less developed ovaries for hibernation (becoming gynes), whereas long-day ...

Patterns of DNA methylation in development, division of labor and hybridization in an ant with genetic caste determination. [PDF]
PLoS ONE, 2012 BACKGROUND: DNA methylation is a common regulator of gene expression, including acting as a regulator of developmental events and behavioral changes in adults.

Recipe for a busy bee: microRNAs in Honey Bee caste determination. [PDF]
PLoS ONE, 2013 Social caste determination in the honey bee is assumed to be determined by the dietary status of the young larvae and translated into physiological and epigenetic changes through nutrient-sensing pathways.

Plasticity in Caste-Fate Determination During the Adult Stage in Temperate Polistes Wasps [PDF]
InsectsThe reproductive division of labor is a fundamental characteristic of eusociality; thus, understanding the caste determination system underlying the reproductive division of labor would shed more light on the evolution of eusociality.

Intragenomic conflict associated with extreme phenotypic plasticity in queen-worker caste determination in honey bees (Apis mellifera) [PDF]
Genome BiologyBackground Caste determination of honey bees (Apis mellifera) exemplifies developmental plasticity, where differences in larval diet result in identical genotypes yielding either long-lived, reproductive queens or short-lived, facultatively sterile ...
