Epigenetic modifications and their relation to caste and sex determination and adult division of labor in the stingless bee Melipona scutellaris

open access: yesGenetics and Molecular Biology, 2017
Stingless bees of the genus Melipona, have long been considered an enigmatic case among social insects for their mode of caste determination, where in addition to larval food type and quantity, the genotype also has a saying, as proposed over 50 years ...

Size-dependent foraging gene expression and behavioral caste differentiation in Bombus ignitus

open access: yesBMC Research Notes, 2009
Background In eusocial hymenopteran insects, foraging genes, members of the cGMP-dependent protein kinase family, are considered to contribute to division of labor through behavioral caste differentiation.

Effect of Larval Topical Application of Juvenile Hormone on Cuticular Chemical Composition of Mischocyttarus consimilis (Vespidae: Polistinae) Females

open access: yesSociobiology, 2020
Juvenile  Hormone  (JH)  is  considered  the  main  determinant  of  caste  in  social insects, though little is known about how this hormone acts in social wasps, especially the independent-founding species.

Micro”bee”ota: Honey Bee Normal Microbiota as a Part of Superorganism

open access: yesMicroorganisms, 2022
Honey bees are model organisms for microbiota research. Gut microbiomes are very interesting for surveys due to their simple structure and relationship with hive production. Long-term studies reveal the gut microbiota patterns of various hive members, as

The function of DNA methylation marks in social insects

open access: yesFrontiers in Ecology and Evolution, 2016
The social arthropods are characterized by a caste-based division of labor that may be influenced by epigenetic effects. One of the most important and widely studied epigenetic mechanisms is DNA methylation.

Linking Genes and Brain Development of Honeybee Workers: A Whole-Transcriptome Approach. [PDF]

open access: yesPLoS ONE, 2016
Honeybees live in complex societies whose capabilities far exceed those of the sum of their single members. This social synergism is achieved mainly by the worker bees, which form a female caste.
