Workers of Reticulitermes flavipes were isolated in groups of increasing numbers to determine the in vitro rates of juvenile hormone (JH) synthesis by individual pairs of corpora allata (CA) as other castes differentiated. Only neotenic reproductives developed in groups of 12.

AbstractExperiments with artificial colonies consisting of only female workers and those of female nymphs and workers of a subterranean termite, Reticulitermes speratus, showed that neotenics (ergatoids and nymphoids) can reproduce parthenogenetically.

AbstractTermite castes are a key example of polyphenism, in which reproductive division of labour is clearly seen in colonies. The reproductive castes in termites include primary and neotenic reproductives; primary reproductives found a new colony whereas neotenics succeed them in the reproductive role when the primary reproductives die or become ...

Termite imagines of Zootermopsis angusticollis (Hagen), while still in the colony as winged individuals, do not show ovary development, although vitellogenin is present in the blood at low levels. When removed from the colony, artificially dealated, and paired, vitellogenin levels rise: subsequently ovaries develop resulting in oviposition ...

AbstractReticulitermes flavipes (Kollar) colonies established by field-collected alates were reared in the laboratory for 11 years. Weights of members of each caste and full-colony censuses were performed regularly; the most recent 2003–2004 data are reported.

The development of Polystoma umthakathi oncomiracidia were studied in experimentally infected Natalobatrachus boneberg tadpoles to establish a normal reference of parasite performance in the natural host. The anteroventral body wall is transparent in these tadpoles and it was possible to follow the destiny of each parasite throughout its life span of ...
