Types and Fecundity of Neotenic Reproductives Produced in 5-Year-Old Orphaned Colonies of the Drywood Termite, Cryptotermes domesticus (Blattodea: Kalotermitidae)

Diversity
Orphaned colonies of Cryptotermes domesticus readily produce replacement reproductives and continue propagation. In this study, we aimed to investigate the production and fecundity of neotenic reproductives in 5-year-old colonies of C.

Queen and king recognition in the subterranean termite, Reticulitermes flavipes: Evidence for royal recognition pheromones. [PDF]

PLoS ONE, 2019
Royal recognition is a central feature of insect societies, allowing them to maintain the reproductive division of labor and regulate colony demography. Queen recognition has been broadly demonstrated and queen recognition pheromones have been identified

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.

Comparative reproductive biology of pre-, imaginal, and neotenic castes of the Asian termiteCoptotermes gestroi(Blattaria, Isoptera, Rhinotermitidae)

Bulletin of Entomological Research, 2022
AbstractThe Asian subterranean termiteCoptotermes gestroiis a worldwide structural pest, although its reproductive biology has been poorly investigated due to a cryptic habit and occurrence of polycalic nests. In this study, we investigated ovarian development and oogenesis in different-aged females ofC.

Molecular basis for the reproductive division of labour in a lower termite [PDF]

BMC Genomics, 2007
Background Polyphenism, the expression of different phenotypes with the same genetic background, is well known for social insects. The substantial physiological and morphological differences among the castes generally are the result of differential gene ...

Neotenic reproductives influence worker caste differentiation in the termite Reticulitermes speratus (Isoptera; Rhinotermitidae) [PDF]

Sociobiology, 2013
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.

Urban Habitat Mosaics Structure Gene Flow but Preserve Genetic Diversity in an Invasive Termite. [PDF]

Ecol Evol
We investigated how urbanization shapes genetic diversity, population structure, and colony organization in the invasive termite Heterotermes tenuis across paired urban‐forest sites in Guadeloupe, using 18 microsatellite loci to genotype 414 workers from 50 nests. While neutral genetic diversity remained comparable between habitats, significant genetic

Cooperative policing behaviour regulates reproductive division of labour in a termite. [PDF]

Proc Biol Sci, 2020
Reproductive conflicts are common in insect societies where helping castes retain reproductive potential. One of the mechanisms regulating these conflicts is policing, a coercive behaviour that reduces direct reproduction by other individuals.

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,

Polystoma australis(Monogenea): Development and reproduction in neotenic parasites [PDF]

South African Journal of Zoology, 1989
Development and reproduction of neotenic Polystoma australis were investigated in natural anuran Kassina and Semnodactylus hosts in South Africa. Newly established parasites attached mainly inside the left branchial chamber. They then migrated so that parasites older than eight days occurred almost exclusively in the right branchial chamber.
