CASTE DEVELOPMENT IN HYMENOPTERA, A MOLECULAR VIEW FOR FARMING IMPROVEMENT OF STINGLESS BEES

open access: yesTropical and Subtropical Agroecosystems
Background: The evolution and genetic elements for the development of the caste is an enigma in Hymenoptera, as well as the total impact that the genetic elements given in the food of the larvae have on the development of bees.

Reproductive Soldier Development Is Controlled by Direct Physical Interactions with Reproductive and Soldier Termites

open access: yesInsects, 2021
In eusocial insects (e.g., ants, bees, and termites), the roles of different castes are assigned to different individuals. These castes possess unique phenotypes that are specialized for specific tasks.

Formosan subterranean termite (Isoptera: Rhinotermitidae) soldiers regulate juvenile hormone levels and caste differentiation in workers [PDF]

open access: yes, 2005
A caste structure is maintained in termite societies and juvenile hormone (JH) is generally regarded as the most important regulator in these termite colonies.

Earnings and Caste: An Evaluation of Caste Wage Differentials in the Nepalese Labour Market [PDF]

open access: yesThe Journal of Development Studies, 2016
This paper examines the sources of wage differentials among castes in Nepal, a country which had, until 1963, an age-old caste-based social division of labour. We use an extended Oaxaca decomposition model with occupation and firm size augmenting the conventionally used measures of human capital endowments.

Caste differentiation pathways in the Neotropical termite \textit{Inquilinitermes microcerus} (Termitidae, Termitinae) [PDF]

open access: yes, 2017
<p>Among social insects, each caste undertakes specific activities in a colony, and their morphologies are likewise specialized for each function.

Genetic variation in South Indian castes: evidence from Y-chromosome, mitochondrial, and autosomal polymorphisms

open access: yesBMC Genetics, 2008
Background Major population movements, social structure, and caste endogamy have influenced the genetic structure of Indian populations. An understanding of these influences is increasingly important as gene mapping and case-control studies are initiated

Dimorphic ovary differentiation in honeybee (Apis mellifera) larvae involves caste-specific expression of homologs of ark and buffy cell death genes. [PDF]

open access: yesPLoS ONE, 2014
The establishment of the number of repeated structural units, the ovarioles, in the ovaries is one of the critical events that shape caste polyphenism in social insects.

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

Effects of Soldier-Derived Terpenes on Soldier Caste Differentiation in the Termite (Reticulitermes flavipes) [PDF]

open access: yes, 2009
Primer pheromones play key roles in regulating division of labor, which is one of the most fundamental and defining aspects of insect sociality. Primer pheromones are chemical messengers that transmit hormone-like messages among colony members; in ...
