Plant microRNAs in larval food regulate honeybee caste development.

open access: yesPLoS Genetics, 2017
The major environmental determinants of honeybee caste development come from larval nutrients: royal jelly stimulates the differentiation of larvae into queens, whereas beebread leads to worker bee fate.

Differential expression of miRNAs related to caste differentiation in the honey bee, Apis mellifera [PDF]

open access: yes, 2016
International audienceAbstractHoney bees are very important eusocial insects and are involved in the pollination of many plants. Queen bees and worker bees can develop from the same fertilized eggs and are thus genetically identical despite their ...

Diet and cell size both affect queen-worker differentiation through DNA methylation in honey bees (Apis mellifera, Apidae). [PDF]

open access: yesPLoS ONE, 2011
Young larvae of the honey bee (Apis mellifera) are totipotent; they can become either queens (reproductives) or workers (largely sterile helpers). DNA methylation has been shown to play an important role in this differentiation. In this study, we examine

Chemical Components of Dufour’s and Venom Glands in Camponotus japonicus (Hymenoptera, Formicidae)

open access: yesInsects, 2023
The Dufour’s and venom glands are the most developed glands connected to the female reproductive organs, playing important roles in defense, foraging, information exchange, and reproduction in ants. The main chemical secretions of these glands vary among

Myosin Gene Expression and Protein Abundance in Different Castes of the Formosan Subterranean Termite (Coptotermes formosanus)

open access: yesInsects, 2012
The Formosan subterranean termite (Coptotermes formosanus) is an important worldwide pest, each year causing millions of dollars in structural damage and control costs. Termite colonies are composed of several phenotypically distinct castes.

Dopamine regulates termite soldier differentiation through trophallactic behaviours [PDF]

open access: yesRoyal Society Open Science, 2016
Caste polyphenism in social insects is regulated by social interactions among colony members. Trophallaxis is one of the most frequently observed interactions, but no studies have been conducted identifying the intrinsic factors involved in this ...

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]

open access: yes, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

Education, caste and occupational differentials in fertility in India

open access: yesEuropean Journal of Geography, 2020
This study analyses the impact of four prominent factors (education, caste, occupation and development) on fertility in India. The study has also analysed the spatial variations of TFR in India. This spatial analysis also helps in identifying the impact of fertility on Development in India. Present study estimates fertility from census that covers all

Production of Castings with Differentiated Surface Properties [PDF]

open access: yesResearch Bulletin of the National Technical University of Ukraine "Kyiv Politechnic Institute", 2017
Problems. Surface layers get the most intensive external influences during the operation of molded parts of machines and mechanisms, therefore their structure and properties determine the operability of products as a whole. To achieve high surface strength and durability of parts, various technological processes are used in the industry, but most of ...
