Dopamine Regulates Termite Soldier Differentiation Through Trophallactic Behaviours [PDF]

Royal 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 ...

Transcriptomics on Social Interactions in Termites: Effects of Soldier Presence

Frontiers in Ecology and Evolution, 2022
The organization of social insect colonies requires sophisticated mechanisms to regulate caste composition according to colony demands. In termites, the soldier caste is responsible for the inhibition of soldier differentiation, but the mechanism ...

Soldier Caste-Specific Protein 1 Is Involved in Soldier Differentiation in Termite Reticulitermes aculabialis

Insects, 2022
Termite soldiers are a unique caste among social insects, and their differentiation can be induced by Juvenile hormone (JH) from workers through two molts (worker–presoldier–soldier).

INSIGHTS OF CASTE DETERMINATIONS IN SOCIAL INSECTS [PDF]

Acta Scientifica Malaysia, 2022
Eusocial insects display caste structures in which reproductive ability is possessed by a single or a few queens while all other colony members act as workers.

TGFβ signaling related genes are involved in hormonal mediation during termite soldier differentiation. [PDF]

PLoS Genetics, 2018
A working knowledge of the proximate factors intrinsic to sterile caste differentiation is necessary to understand the evolution of eusocial insects. Genomic and transcriptomic analyses in social hymenopteran insects have resulted in the hypothesis that ...

Upregulation of Hox genes leading to caste-specific morphogenesis in a termite

EvoDevo, 2023
Background In social insects, interactions among colony members trigger caste differentiation with morphological modifications. In termite caste differentiation, caste-specific morphologies (such as mandibles in soldiers, genital organs in reproductives ...

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

Insects, 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.

Screening of reference genes for microRNA analysis in the study of solider caste differentiation of Formosan subterranean termite Coptotermes formosanus Shiraki

Scientific Reports, 2023
The soldier caste differentiation is a complex process that is governed by the transcriptional regulation and post-transcriptional regulation. microRNAs (miRNAs) are noncoding RNAs that control a wide range of activities.

Structural properties of native and conjugated black soldier fly (Hermetia illucens) larvae protein via Maillard reaction and classification by SIMCA

Heliyon, 2021
Black soldier fly (Hermetia illucens) has received considerable interest as an alternative protein source. Aqueous solutions of black soldier fly larvae (BSFL) protein and glucose (2:1 w.w−1, pH 9) were heated at 50, 70 and 90 °C, for 2–10 h at 2 h ...

Caste-specific expressions and diverse roles of takeout genes in the termite Reticulitermes speratus

Scientific Reports, 2023
Acquisition of novel functions caused by gene duplication may be important for termite social evolution. To clarify this possibility, additional evidence is needed. An important example is takeout, encoding juvenile hormone binding protein. We identified
