SummaryThe nests of the Neo-GuineanNasutitermes polygynus Roisin and Pasteels and the NeotropicalN. costalis (Holmgren) are polycalic. Seventy percent of theN. polygynus nests and half theN. costalis nests were found to be devoid of royal nodule and reproductives. Two polycalic systems ofN. polygynus revealed the presence of functional reproductives in more than one calie, thus suggesting a process of colony reproduction by budding.Multiple imaginal queens are extremely frequent in both species…

The conditions necessary for natural selection to favor pofyglrny are examined, considering separatefy the grouping of dresses after the nuptial flight (pleonetrosis) and the differentiation of sexuals in a pre-existing society, âs replacement reproductives or in a budded nest.

Polycalic nest systems and levels of aggression of Constrictotermes cyphergaster (Isoptera, Termitidae, Nasutitermitinae) in the semi-arid region of Brazil.

The seasonality ofpolycalism in C. cyphergaster is one of the causes of the increase in density of new nests during the wet season, and it was observed that, after foraging, part of the termite population would return to the largest nest in volume of the polycalic colonies and part would stay in the satellite nests.

Reticulitermes flavipes (Isoptera: Rhinotermitidae) colonies: reproductive lifespans, caste ratios, nesting and foraging dynamics, and genetic architecture

These complete colonies demonstrated foraging and nesting activities of socially intact families and provided unprecedented demographic information regarding colony growth rate and longevity, lifespan of founding reproductives, and the response of colonies to the loss of primary kings and queens.

Patterns of neotenic differentiation in a subterranean termite, Reticulitermes speratus (Isoptera: Rhinotermitidae)

The results suggested that the number of differentiated ergatoids was restricted by the existence of nymphs or nymphoids in a colony, and attack reflecting conflict between colony members is probably an important mechanism to control neotenic emergence.

Queen fecundity and reproductive skew in the termite Nasutitermes corniger

Oviposition rates in the neotropical termite Nasutitermes corniger are analyzed to hypothesize that the incentive to tolerate reproduction by other females is especially pronounced for heavier queens, because these queens are close to the limit of their own reproductive capacity.

Comparative Nesting Habits and Colony Composition of Three Arboreal Termites (Isoptera: Termitidae) in Trinidad and Tobago, West Indies

Analysis of colonies shows the expected similarity in the two species of nasute-termites, M. arboreus and N. ephratae, which are consistent with much greater withinspecies variation among habitats than among species in the same habitat.

Intraspecific interactions in a community of arboreal nesting termites (Isoptera: Termitidae)

Lack of agonism between some colonies suggests the possibility of colony fusion and gene exchanges without nuptial flights in cotrast, and anagonism between colonies may result in the elimination of the weakest colonies or in trail divergence, maintaining this mosaic.

Termite colony ontogeny: supplemental data in the long-term assessment of reproductive lifespan, female neotenic production and colony size in Reticulitermes flavipes (Isoptera: Rhinotermitidae)

Reticulitermes flavipes colonies established by field-collected alates were reared in the laboratory for 11 years, and with the exception of primary queens from one genetic lineage, mean weights for all castes had increased since 2001.

Impact of orphaning on field colonies of Southeast Asian Macrotermes gilvus (Hagen) and M. carbonarius (Hagen) (Termitidae, Macrotermitinae)

It is demonstrated that the presence of sexual castes (nymphs or alates) at the time of orphaning does not necessarily guarantee the success of colonies in re-establishing themselves as breeding colonies.

Nest Architecture, Colony Composition and Feeding Substrates of Nasutitermes coxipoensis (Isoptera, Termitidae, Nasutitermitinae) in Subtropical Biomes of Northeastern Argentina

The external and internal characteristics of the nests were similar to descriptions from other sites although it was not possible to differentiate the royal cell, and the societies were monogynic and the queens laid eggs throughout the year.



Polygyny in the Neotropical termite Nasutitermes corniger: life history consequences of queen mutualism

Data on queen weight and morphological features, and on colony composition, show that queens in polygynous nests are young and that a transition from polygyny to monogyny probably occurs after several years, which is of significance as an example of a further ecological and evolutionary convergence between the phylogenetically independent orders Isoptera and Hymenoptera.

Imaginal polymorphism and polygyny in the Neo-Guinean termiteNasutitermes princeps (Desneux)

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.

Polygyny in termites: Multiple primary queens in colonies ofNasutitermes corniger (Motschuls) (Isoptera: Termitidae)

It is predicted that polygyny will prove most common in habitats where the probability of survival is low and rapid colony growth is advantageous, and in areas of young second growth in the Republic of Panamá, polygynous colonies were found commonly.

Replacement of reproductives in Nasutitermes princeps (Desneux) (Isoptera: Termitidae)

The data indicate that the replacement of the primary queen after her accidental death cannot by itself account for the high rate of polygyny encountered in N. princeps.

Polycalic colonies of some mound building termites (Isoptera: Termitidae) in northeastern Australia

The relationships of adjacent mounds of five widely distributed species of termites, at two sites south and southwest of Townsville in north Queensland have been examined and it has been shown that four of these species are polycalic, with up to eight mounds comprising a single colony.

Caste and ecology in the social insects.

In this pathbreaking and far-reaching work George Oster and Edward Wilson provide the first fully developed theory of caste evolution among the social insects and construct a series of mathematical models to characterize the agents of natural selection that promote particular caste systems.

Replacement of the Royal Pair in Macrotermes Michaelseni

Measurements of the replacement queens showed that they can become fully physogastric within 7 months, and it was not possible to find out at what time after the removal a new royal pair was accepted.

The nasute soldiers of the neotropical termite Nasutitermes costalis function as scouts by exploring new terrain for food in advance of the worker caste and regulate foraging activity by laying
