ResumoSUMMARY Thousands of free-living mites were collected near Hamburg from areas where wild rabbits were numerous and heavily infected with anoplocephaline cestodes. The mites were dissected and cysticercoids were removed from Scutovertex minutus, Scheloribates laevigatus and Pelops tardus. The larvae were fed to young, domestic rabbits and a cysticercoid froIn S. minutus developed into a sexually mature specimen of Cittotaenia ctenoides. Other mites, collected from areas where they would not be exposed to eggs of anoplocephaline cestodes, were fed eggs of Cittotaenia ctenoides and C. denticulata. Developmental stages of C. ctenoides were recovered from the body cavities of Scutovertex minutus, Galumina obvious, Pelops acromius, Liacarus coracinus, Notaspis coleoptratus, Liebstadia similis, Xenillus tegeocranus, Scheloribates laevigatus, Cepheus cepheiformis, Trichoribates incisellus, and Galumna This content downloaded from 157.55.39.76 on Wed, 20 Apr 2016 06:52:21 UTC All use subject to http://about.jstor.org/terms THE JOURNAL OF PARASITOLOGY nervosus. The larvae attained the cysticercoid stage in the first seven of the species listed and, since development appeared normal in the other mites, it is possible that they might have completed their development if the hosts had lived long enough. Development of C. denticulata was observed in S. minutus, X. tegeocranus, C. cepheiformis, T. incisellus, S. laevigatus, and L. coracinus, although only S. minutus lived long enough in the cultures for cysticercoids to be produced. Infections were obtained only in oribatid mites. None of the rabbits fed cysticercoids from experimentally infected mites gave evidence of infection and it is probable that these larvae were not entirely mature. The developmental stages of C. ctenoides and C. denticulata in the intermediate hosts are described from experimental infections. The development of C. ctenoides, C. denticulata and C. pectinata in the final hosts is described from natural infections. No evidence was found to support the idea that these tapeworms migrate from the intestine to the body cavity of normal, live, rabbits.
