Transcriptomic and Functional Analyses of Phenotypic Plasticity in a Higher Termite, Macrotermes barneyi Light

Frontiers in Genetics, 2019
Eusocial termites have a complex caste system, which leads to the division of labor. Previous studies offered some insight into the caste differentiation in lower termites; however, few studies were focusing on the molecular mechanisms of higher termites

Uncovering the Changing Gene Expression Profile of Honeybee (Apis mellifera) Worker Larvae Transplanted to Queen Cells

Frontiers in Genetics, 2018
The reproductive division of labor, based on caste differentiation in social insects, is of great significance in evolution. Generally, a healthy bee colony consists of a queen and numerous workers and drones.

The Waning Caste System of The Gambia

Turkish Academic Research Review
This study examines how caste shapes social relations in The Gambia through the lens of Blalock’s (1967) Group Threat Hypothesis and assesses the extent to which Western education can be credited with addressing caste-related concerns.

Social interactions affecting caste development through physiological actions in termites

Frontiers in Physiology, 2014
A colony of social insects is not only an aggregation of individuals but also a functional unit. To achieve adaptive social behavior in fluctuating environmental conditions, in addition to coordination of physiological status in each individual, the ...

Population Growth Characteristics of Incipient Colonies of the Eastern Subterranean Termite, Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae)

Sociobiology, 2014
Growth of Reticulitermes flavipes (Kollar) incipient colonies during their first year was documented via a monthly destructive sampling census of 15 unique colonies, each headed by an inbred primary pair, for a total of 180 colonies.

Honeybee Venom Proteome Profile of Queens and Winter Bees as Determined by a Mass Spectrometric Approach

Toxins, 2015
Venoms of invertebrates contain an enormous diversity of proteins, peptides, and other classes of substances. Insect venoms are characterized by a large interspecific variation resulting in extended lists of venom compounds.

Changes in Alternative Splicing in Apis Mellifera Bees Fed Apis Cerana Royal Jelly

Journal of Apicultural Science, 2014
The Western honey bee (Apis mellifera) is a social insect characterized by caste differentiation in which the queen bee and worker bees display marked differences in morphology, behavior, reproduction, and longevity despite their identical genomes.

Molecular determinants of caste differentiation in the highly eusocial honeybee Apis mellifera [PDF]

, 2007
Background In honeybees, differential feeding of female larvae promotes the occurrence of two different phenotypes, a queen and a worker, from identical genotypes, through incremental alterations, which affect general growth, and character state ...

Evolutionary diversification of alternative splicing along a social complexity gradient in aculeata insects

Frontiers in Ecology and Evolution
The evolution of animal sociality is characterized by profound phenotypic differentiation originating from a shared genome. While differential gene expression is known to contribute to caste development, the evolutionary dynamics of post-transcriptional ...
