SummaryThe existence of a worker caste in Prorhinotermes inopinatus was determined with the help of biometrical analyses and morphological observations. No dichotomy between alate and worker lines was detected among the young larval instars. Mandible sclerotization and wear show that the larvae become active by the fourth instar in mature colonies, and by the third in incipient ones. Prothoracic finger-shaped expansions characterize the most dependent larval instars. The antennal structure is… Expand

Figures and Tables from this paper

Caste morphology and development in termitogeton nr. planus (insecta, isoptera, rhinotermitidae)
TLDR
The traditional definitions of the terms larvae, nymphs, and pseudergates should be revised because they cannot be satisfactorily applied to the castes of Termitogeton, a putative undescribed species from New Guinea. Expand
Comparative studies on alate wing formation in two related species of rotten-wood termites: Hodotermopsis sjostedti and Zootermopsis nevadensis (Isoptera, Termopsidae)
TLDR
It is suggested that heterochronic evolutionary change accounts for the compression of nymphal development into a single instar in the rotten-wood termite Hodotermopsis sjostedti. Expand
Polymorphism in the giant cocoa termite,Neotermes papua (Desneux)
TLDR
By pinpointing the existence of a large pool of pluripotent individuals, in which the penultimate nymphal stage mingles with pseudergates, the present study reveals a great similarity between Neotermes and Prorhinotermes, and suggests that this developmental schema might be generally applicable to termites devoid of a permanent worker caste. Expand
Secondary queens in the parthenogenetic termite Cavitermes tuberosus develop through a transitional helper stage
TLDR
It is highlighted that neotenic queens derive from third and fourth instar nymphs displaying peculiar morphological traits, here termed “aspirants,” most of which are produced by parthenogenesis. Expand
Reduction of a nymphal instar in a dampwood termite: heterochronic shift in the caste differentiation pathways
TLDR
The developmental events for wing formation are compacted into a single nymphal instar in H. sjostedti, and as a result, the unique wing formation is seen to compensate for the spatial restriction inside small wing buds, leading to the completion of functional wings. Expand
Developmental Pathways of Psammotermes hybostoma (Isoptera: Rhinotermitidae): Old Pseudergates Make up a New Sterile Caste
TLDR
Large worker-like individuals deviate late and do not perform worker tasks, they cannot be considered homologous to the true workers of Termitidae and advanced Rhinotermitidae, but they provide a novel example of the evolution of sterile immatures in termites. Expand
Developmental pathways of Glossotermes oculatus (Isoptera, Serritermitidae): at the cross‐roads of worker caste evolution in termites
TLDR
It is argued that pseudergates of G. oculatus are close to a point where the species could easily shift toward the differentiation of a true worker caste, and that G. Oculatus pinpoints a new possible route for the evolution of true workers from pseudergate. Expand
Temporal polyethism in incipient colonies of the primitive termiteZootermopsis angusticollis: A single multiage caste
TLDR
Small colony size, low oviposition rate, simple nest architecture, a lack of spatial association of tasks, and the potential for attaining reproductive status appear to be associated with the lack of age-related behavioral specialization in Z. angusticollis, which is likely a consequence of its nesting habits and physiological and developmental constraints. Expand
The morphology and ontogeny of the exocrine glands of Prorhinotermes simplex (Isoptera: Rhinotermitidae)
TLDR
The structure of the exocrine glands of Prorhinotermes simplex was investigated using histological techniques and the development of the frontal, mandibular, labial, sternal, posterior sternal and tergal glands is described. Expand
The ontogeny of soldiers in Prorhinotermes simplex (Isoptera, Rhinotermitidae)
TLDR
The observed patterns of soldier production in P. simplex correspond well to its ecological strategy of an advanced single-site nester able to migrate and form foraging groups. Expand

A Re-Examination of the Development of Castes in Mastotermes Darwiniensis Froggatt (Isoptera).
TLDR
The developmental pathways in mature field colonies of Mastotermes darwiniensis are morphologically distinguishable after the moult to the second instar; the larvae and early workers in field colonies are smaller than those of the same instar in incipient colonies. Expand
Ontogenetic development and evolution of the worker caste in termites
TLDR
The definition of the worker caste and the current theories explaining its evolution are reexamined after a critical reappraisal of data on post-embryonic development and on the basis of ontogenic, morphologic and functional criteria, termite workers are defined. Expand
Termite colony dynamics as revealed by the sex- and caste-ratios of whole colonies ofIncisitermes schwarzi banks (Isoptera: Kalotermitidae)
TLDR
There was an excess of males among the workers of colonies that had begun to form nymphs and alates, and among the soldiers of all colonies, and the unusual chromosomal mechanism of sex determination was discussed. Expand
Pathways of Caste Development in the Lower Termites
TLDR
It is discussed that lower termites comprise several evolutionary lines and do not constitute a systematic unit, and that the developmental pathway well evidenced in Kalotermes flavicollis is general for the Kalotermitidae and Termopsidae. Expand
Caste Development in Mastotermes and Kalotermes: Which is Primitive?
TLDR
The chapter explains the two groups of developmental pathways which serves as classical models for the interpretation of caste development, and its evolution in termites, both the linear pathway of Kalotermes flavicollis and the bifurcated pathways of the termitids. Expand
Imaginal polymorphism and polygyny in the Neo-Guinean termiteNasutitermes princeps (Desneux)
TLDR
The evolution of microimaginal reproductives through precocious differentiation of nymphs could be interpreted as the result of intracolonial competition amongst nymphS for reproductive status in a species in which reproductive status can occasionally be attained in the parental colony and in which swarming is not the only normal way of reproduction. Expand
Caste developmental potentialities in the termite Nasutitermes novarumhebridarum
TLDR
It is suggested that N. novarumhebridarum caste potentialities are adapted to channelling a maximum of resources into the production of dispersing alates that can colonize new nest sites. Expand
Differentiation of worker‐derived intercastes and precocious imagoes after queen removal in the Neo‐Guinean termite Nasutitermes princeps (Desneux)
TLDR
The developmental pathways of these intercastes were studied with the help of multivariate techniques that revealed two main lines, one ending in a new “giant soldier” morph, the other proceeding toward the differentiation of nymphal characters, i.e., wing pads and compound eyes. Expand
Caste determination and differentiation with special reference to the genus reticulitermes (Isoptera)
TLDR
From evidence to date, it must be granted that both intrinsic and extrinsic factors may play a role in the production of castes and the delay in appearance of demonstrable caste differences until the third stadium in the genus Reticulitermes at least admits of an opportunity for extrinsics to be effective. Expand
The Caste System in Higher Termites
TLDR
The soldier caste is much more diversified in the higher than in the lower termites, but this evolution is integrated in various defensive strategies, in relation with foraging and building behavior. Expand
