Termite Valkyries: Soldier-Like Alate Termites From the Cretaceous and Task Specialization in the Early Evolution of Isoptera

Frontiers in Ecology and Evolution, 2022
In several insect eusocial lineages, e.g., some aphids, thrips, ants, some stingless bees, and termites, task specialization is brought to its climax with a sterile soldier caste solely devoted to colony defense.

Development of neotenics induced by a temporary absence of functional reproductives in Kalotermes flavicollis (Isoptera: Kalotermitidae) [PDF]

European Journal of Entomology, 2005
The effect of removing the functional pair of Kalotermes flavicollis from an experimental colony for 12, 24 or 48 h and the repeated removal for a particular number of hours per day (2, 4, 6, 12, 18, 20, and 22 h) was studied. An absence of the functional pair for 12 h had no affect on the development of new neotenics, whereas 24-h absence induced the ...

Physiological and developmental mechanism of regressive molt in a damp-wood termite Hodotermopsis sjostedti

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 ...

Sex-specific inhibition and stimulation of worker-reproductive transition in a termite [PDF]

, 2017
In social insects, the postembryonic development of individuals exhibits strong phenotypic plasticity in response to environment, thus generating the caste system.

Genetic analysis of population structure and reproductive mode of the termite Reticulitermes chinensis snyder. [PDF]

PLoS ONE, 2013
The subterranean termite Reticulitermes chinensis Snyder is an important pest of trees and buildings in China. Here, we characterized genetic structure and reproductive modes of R. chinensis from China for the first time. A total of 1,875 workers from 75

Morphology and gonad development of normal soldiers and reproductive soldiers of the termite Zootermopsis nevadensis nevadensis (Isoptera, Archotermopsidae)

ZooKeys, 2011
Reproductive or neotenic soldiers of the Archotermopsid Zootermopsis nevadensis nevadensis (Hagen) are compared to sterile soldiers and primary male reproductives.

Ability of primary and secondary reproductives to inhibit the development of neotenics in Kalotermes flavicollis (Isoptera: Kalotermitidae) [PDF]

European Journal of Entomology, 2004
The inhibitory potential of primary and secondary reproductives was studied using half-orphaned colonies of Kalotermes flavicollis. Both primary and secondary reproductives (neotenics) were equally effective in inhibiting the development of replacement reproductives. Single females totally inhibited the development of female secondary reproductives but

Termites, hemimetabolous diploid white ants?

Frontiers in Zoology, 2008
Ants and termites are the most abundant animals on earth. Their ecological success is attributed to their social life. They live in colonies consisting of few reproducing individuals, while the large majority of colony members (workers/soldiers) forego ...

ACA DGE data(Single cell RNA-seq part_larva neotenic axolotls)

, 2022
Mexican axolotl (Ambystoma mexicanum) is a promising tetrapod model in regeneration and developmental studies. Neotenic axolotl rarely undergoes spontaneous metamorphosis.
