“…A few other congeneric species exhibit more extensive levels of polygamy (Thorne, 1984;Roisin & Pasteels, 1986b) generated through the full range of developmental pathways (Thorne, 1982;Roisin & Pasteels, 1986a). This includes N. costalis (Roisin & Pasteels, 1986b) which is sympatric with N. nigriceps throughout parts of its range on Jamaica.…”

Monogamy and inbreeding are often thought to characterize the breeding system of termite societies. However, few studies have employed genetic markers to ascertain either the genetic structure of single colonies or the extent of local inbreeding. This study employs allozyme analysis to investigate the breeding system of Nasutitermes nigriceps with respect to the number of reproductives contributing to single colonies, and the level of inbreeding within and among local colonies. The majority of the 136 nests examined from three study sites showed patterns of protein polymorphism consistent with their origin from a single mated pair, establishing that monogamy is indeed the predominant mode of reproduction. A small proportion of colonies (N = 7) had genotypic frequencies suggesting that offspring were not all full-siblings. The genetic composition of all colonies appeared stable through a one-year interval, suggesting that the observed genetic attributes represent relatively persistent reproductive associations. Wright's (1978) F-statistics showed moderate differentiation among study sites, indicative of restricted gene flow and the occurrence of inbreeding at a regional scale. However, mating appeared to be random at single sites as the inferred genotypic frequencies of colony progenitors did not deviate from Hardy-Weinberg expectations, indicating little inbreeding in the study populations.

“…In several Isoptera groups, when one of the primary reproductive dies or becomes old, they are replaced by secondary reproductives that can have several origins: "adultoids" are derived from the imagoes, "nymphoids" are derived from nymphs and retain the wing buds, "ergatoids" are derived from workers and have no evidence of wing buds (NOIROT 1969;WILSON 1971;BRIAN 1979;COSTA-LEONARDO et al 1996;THORNE 1996;MYLES 1999). If any of these reproductive types differentiates within a colony while primaries ones are still alive and reproducing, are called supplementary (THORNE 1996) and if they developed after primaries die, they will be replacement reproductives (MYLES 1999).…”

“…If any of these reproductive types differentiates within a colony while primaries ones are still alive and reproducing, are called supplementary (THORNE 1996) and if they developed after primaries die, they will be replacement reproductives (MYLES 1999). In "higher" termites, the factors that trigger supplementary determination are: greater population diffusion, perturbations in rates of population growth, seasons, newly discovered resources items, or architectural extensions of the colony (polycalism) (MYLES 1999).…”

ABSTRACT. Constrictotermes cyphergaster (Silvester, 1901) builds arboreal nests in Brazilian Cerrado stricto sensu, which are frequently cohabited by inquilines termites and by termitophiles. In a study made at the Parque Estadual da Serra de Caldas Novas, Goiás, Brazil, there were four nests with multiple reproductives, and secondary reproductives were found in 26 nests. Nymphs of Inquilinitermes were more abundant (9,47%) than nymphs of C. cyphergaster (0,78%).

“…Colonies of termites have an exceptional number of sterile individuals, the workers and soldiers, that are responsible for purveyance and defence of the nest, and by one or more fertile females, the queens, which allocate all their time and energy in reproduction (Thorne, 1984).…”

The number of reproductive individuals present in colonies of Nasutitermes sp. was analysed, and its possible reproductive strategy discussed. Twenty-four nests were collected and opened, and a single queen and king were found in 17 of them. In the other 7 nests, no queen or king were neither found, nor any other reproductive individual. All quee ns were weighed, and the number of eggs laid by them was counted. No relationship between the volume of the nests and the weight of their respective queens was found, but the number of eggs laid by the queens during an hour was positively correlated to their weight .Key words: Nasutitermes, Isoptera, Termitidae, reproduction, polygyny. RESUMO Mecanismo reprodutivo em Nasutitermes sp. (Isoptera: Termitidae)Foi analisado o número de reprodutores presentes nas colônias de Nasutitermes sp., discutindo suas possíveis estratégias reprodutivas. Vinte e quatro ninhos de Nasutitermes sp. foram coletados e abertos sendo encontrado uma única rainha e um rei em 17 deles. Nos outros 7, o casal real não foi encontrado e também nenhum outro tipo de reprodutores. Todas as rainhas foram pesadas, sendo contado o número de ovos postos por elas num período de uma hora. Nunhuma relação entre o volume das colônias e o peso de suas respectivas rainhas foi encontrada mas, as análises indicam uma correlação positiva e significativa entre o número de ovos postos por elas durante uma hora e seus pesos.
