Oribatid mites (Acari: Oribatida) are an important component in all biological processes that take part in the soil ecosystem. Some of them playas intermediate hosts of tapeworms (Cestoda). This report presents the study results on the role of oribatid mites as intermediate hosts for Cestoda: Anoplocephalidae, and to review their role of transmission for Cestoda in the soil ecosystem of Vietnam. In the soil ecosystem of the grassland and cultivated land within Cat Ba National park, the percentage of oribatid individuals folind to be cestode carriers is in following descending order: Spring Autumn Summer Winter. The percentage of oribatid species found to be cestode carriers is in following descending order: Summer Winter Autumn Spring. Ten tapeworm species (Cestoda: Anoplocephalidae) are known to parasitize 21 animal species of Vietnam, with oribatid mites being intermediate hosts. Introduced was also the two-host life cycle of tapeworm Bertiella species, with oribatid mites serving as intermediate hosts prior to transmission to the definitive host.
