Abstract

Seinura demani was reared on five species of bacterial feeding nematodes and 3 fungus feeding species. Under culture conditions prey were recognised on contact; there was no evidence of an ability to track victims. S. demani is a bisexual species, its life-history includes one juvenile stage within the egg, two post-hatch juvenile stages, and the adult. Development of all stages are described and measurements given. In cultures incubated at 20°C, the generation time is 41/2-5 days. Male S. demani are attracted to pre-adult moulting females and are retained in their immediate vicinity until the moult is completed. Mating behaviour and copulation are described. Descriptions of behaviour are based on observation, not on experiments, and should therefore be considered as items for further research. Conclusions drawn from the observations are tentative at this stage.
