Morphological Caste Differences in Three Species of the Neotropical Genus Clypearia (Hymenoptera: Polistinae: Epiponini)

open access: yesPsyche: A Journal of Entomology, 2010
Clypearia is a rare genus of swarm-founding Neotropical wasp whose biology is very little known. Morphological castes differences, condition of ovaries, relative age, and color pattern differences were analyzed in three species of Clypearia ...

The Phenotypic Effects of Royal Jelly on Wild-Type D. melanogaster Are Strain-Specific.

open access: yesPLoS ONE, 2016
The role for royal jelly (RJ) in promoting caste differentiation of honeybee larvae into queens rather than workers is well characterized. A recent study demonstrated that this poorly understood complex nutrition drives strikingly similar phenotypic ...

The genetic regulatory network mediating caste differentiation in ants:a transcriptomic view [PDF]

open access: yes, 2019
An ant colony can be conceptualized as a higher-level organism with permanent reproductive division of labour between inseminated queen (germ) and worker (soma) individuals, analogous to the germ-cells and somatic cells in a multicellular organism.

Evolutionary relationship of fat body endoreduplication and queen fecundity in termites

open access: yesEcology and Evolution, 2019
Endoreduplication or nuclear genome replication without cell division is widely observed in the metabolically active tissues of plants and animals. The fat body cells of adult female insects produce abundant yolk proteins and become polyploid, which is ...

Nature versus nurture in social insect caste differentiation [PDF]

open access: yesTrends in Ecology & Evolution, 2010
Recent evidence for genetic effects on royal and worker caste differentiation from diverse social insect taxa has put an end to the view that these phenotypes stem solely from a developmental switch controlled by environmental factors. Instead, the relative influences of genotypic and environmental effects on caste vary among species, ranging from ...

Molecular basis of caste differentiation in pharaoh ant:insights from process of ovarian development [PDF]

open access: yes, 2021
Reproductive division of labor is a hallmark of the social insects. The individuals produced by the same mother queens can develop either to the reproductive caste or non-reproductive caste fate.

Special recipe from pollens for the caste determination of honeybees [PDF]

open access: yesExRNA, 2019
Honeybee caste differentiation is regulated by multiple factors. Here we comment an article published on August 31, 2017, Plos Genetics, which show that miRNAs from pollen may affect honeybee caste formation.

Mechanisms regulating caste differentiation in an aphid social system [PDF]

open access: yesCommunicative & Integrative Biology, 2010
For evolution and maintenance of the social systems of insect colonies, caste production should be controlled in response to external cues so that caste ratio in the colony is kept at an optimal range. Recent developments using artificial diet rearing techniques have revealed an underlying mechanism for adaptive control of caste production in a social ...

Differential protein expression in honeybee (Apis mellifera L.) larvae: underlying caste differentiation. [PDF]

open access: yes, 2010
Honeybee (Apis mellifera) exhibits divisions in both morphology and reproduction. The queen is larger in size and fully developed sexually, while the worker bees are smaller in size and nearly infertile.

Multiple Convergent Origins of Workerlessness and Inbreeding in the Socially Parasitic Ant Genus Myrmoxenus. [PDF]

open access: yesPLoS ONE, 2015
The socially parasitic ant genus Myrmoxenus varies strongly in fundamental life history traits, such as queen-worker ratio, the timing of sexual production, and mating behavior.
