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.

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 ...

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 in Reticulitermes labralis (Isoptera: Rhinotermitidae): a comparative study. [PDF]
J Insect Sci, 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 ...

Plastic brain structure changes associated with the division of labor and aging in termites. [PDF]
Dev Growth Differ, 2023 Division of labour is a prominent feature of social insect societies, where different castes engage in different specialised tasks. As brain differences are associated with behavioural differences, brain anatomy may be linked to caste polymorphism. Here,

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 ...

The Unusual Neotenic System of the Asian Dry Wood Termite, Neotermes koshunensis (Isoptera: Kalotermitidae) [PDF]
Sociobiology, 2013 In most lower termites, colonies are headed by neotenic reproductives of both sexes after the primary reproductives (i.e., the queen and king) are lost.

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.

Physiological and developmental mechanism of regressive molt in a damp-wood termite Hodotermopsis sjostedti [PDF]
Frontiers in Ecology and Evolution, 2023 In some species of termites, a part of nymphs can undergo “regressive molt,” in which imaginal characters such as wing buds and body size are reduced. The function of regressive molt is thought to be a regulatory mechanism controlling caste composition ...
