Male neotenic reproductives accelerate additional differentiation of female reproductives by lowering JH titer in termites [PDF]
Scientific Reports, 2020 Eusocial insects exhibit reproductive division of labor, in which only a fraction of colony members differentiate into reproductives. In termites, reproductives of both sexes are present in a colony and constantly engaged in reproduction.

Reproductive Soldier Development Is Controlled by Direct Physical Interactions with Reproductive and Soldier Termites [PDF]
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.

Neotenic reproductives influence worker caste differentiation in the termite Reticulitermes speratus (Isoptera; Rhinotermitidae) [PDF]
Sociobiology, 2014 Division of labor among castes in social insect colonies increases ergonomic efficiency and colony-level fitness, and has played a key role in the ecological success of social insects.

Regulatory Mechanisms Underlying the Differentiation of Neotenic Reproductives in Termites: Partial Release From Arrested Development [PDF]
Frontiers in Ecology and Evolution, 2021 Eusocial insects exhibit reproductive division of labor, in which only a part of colony members differentiates into reproductives. In termite colonies, the division of labors is performed among multiple types of individuals (i.e., castes), such as ...

The Development of Adultoid Reproductives and Brachypterous Neotenic Reproductives From the Last Instar Nymphs inReticulitermes labralis(Isoptera: Rhinotermitidae): A Comparative Study [PDF]
Journal of Insect Science, 2015 Secondary reproductives develop primarily from nymphs. However, they have been rarely studied; in particular, the development of adultoid reproductives (AR) with floppy wings is still unclear. In this study, the change in juvenile hormone (JH) levels, vitellogenin gene expression, and oogenesis during the development of AR and brachypterous neotenic ...

Multiple male and female reproductive strategies and the presence of a polyandric mating system in the termite Reticulitermes labralis (Isoptera:Rhinotermitidae) [PDF]
Sociobiology, 2014 Reproductive systems of termite colonies may involve the number of individuals in the reproductive caste and the copulatory selectivity of reproductive individuals (i.e., polyandry or polygamy), both of which directly impact the fertility and genetic ...

Characterization of the transcriptomes and cuticular protein gene expression of alate adult, brachypterous neotenic and adultoid reproductives of Reticulitermes labralis [PDF]
Scientific Reports, 2016 AbstractThe separation of primary reproductive and secondary reproductive roles based on the differentiation of alate adults and neotenic reproductives is the most prominent characteristic of termites. To clarify the mechanism underlying this differentiation, we sequenced the transcriptomes of alate adults (ARs), brachypterous neotenics (BNs) and ...

Upregulation of Hox genes leading to caste-specific morphogenesis in a termite [PDF]
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 ...

Diversity of Termite Breeding Systems [PDF]
Insects, 2019 Termites are social insects that live in colonies headed by reproductive castes. The breeding system is defined by the number of reproductive individuals in a colony and the castes to which they belong.

Widespread occurrence of asexual reproduction in higher termites of the Termes group (Termitidae: Termitinae) [PDF]
BMC Evolutionary Biology, 2019 Background A decade ago, the mixed reproductive strategy Asexual Queen Succession (AQS) was first described in termites. In AQS species, the workers, soldiers and dispersing reproductives are produced through sexual reproduction, while non-dispersing ...
