Complex hybrid origin of genetic caste determination in harvester ants [PDF]
Nature, 2003 Caste differentiation and division of labour are the hallmarks of insect societies and at the root of their ecological success. Kin selection predicts that caste determination should result from environmentally induced differences in gene expression, a ...

Insects, 2023 There is growing evidence that paper wasps’ (Polistes’) fate as workers or reproductive females (gynes) is affected by cues that exist at the larval stage and during eclosion.

Hybridization enables the fixation of selfish queen genotypes in eusocial colonies
Evolution Letters, 2021 A eusocial colony typically consists of two main castes: queens that reproduce and sterile workers that help them. This division of labor, however, is vulnerable to genetic elements that favor the development of their carriers into queens.

Caste-biased Expression of fem and Amdsx Genes in Apis mellifera ligustica (Hymenoptera: Apidae)
Sociobiology, 2021 Sex determination and caste differentiation are two crucial processes for morphology building in honeybees. It is unclear whether there is an interaction between these two processes.

Differential gene expression and protein abundance evince ontogenetic bias toward castes in a primitively eusocial wasp. [PDF]
PLoS ONE, 2010 Polistes paper wasps are models for understanding conditions that may have characterized the origin of worker and queen castes and, therefore, the origin of paper wasp sociality.

Genetics and Molecular Biology, 2021 Social organization in highly eusocial bees relies upon two important processes: caste differentiation in female larvae, and age polyethism in adult workers. Juvenile Hormone (JH) is a key regulator of both processes.

What Kills the Hindgut Flagellates of Lower Termites during the Host Molting Cycle?
Microorganisms, 2017 Subsocial wood feeding cockroaches in the genus Cryptocercus, the sister group of termites, retain their symbiotic gut flagellates during the host molting cycle, but in lower termites, closely related flagellates die prior to host ecdysis.

Genetic components to caste allocation in a multiple-queen ant species. [PDF]
, 2011 Reproductive division of labor and the coexistence of distinct castes are hallmarks of insect societies. In social insect species with multiple queens per colony, the fitness of nestmate queens directly depends on the process of caste allocation (i.e ...
