【 摘 要 】

The aim of this work was to identify the components of zooplankton that act as intermediate hosts of cestodes. One hundred and ninety four copepods of the suborder Calanoida, 317 copepods of the suborder Cyclopoida and 4240 cladocerans were collected in the Juqueri reservoir, in the state of São Paulo, from January to August, 2003. Only Copepods Calanoida of the genus Notodiaptomus sp. Kiefer were found to be infected and contained two distinct forms of metacestodes. The metacestodes, denominated Met 1 (order Proteocephalidea) and Met 2 (order Cyclophyllidea), had the following rates of prevalence and mean intensities of infection: Met 1 - 2.06% and 64 larvae/copepod and Met 2 - 0.52% and one larvae/copepod. The positive copepods were collected at the margins of the reservoir during the day. This finding suggest that parasitism may lead to a change in the behavior of the copepods and make them more susceptible to predation in shallow water.
