In the field of helminthology, the life cycle of an organism not only brings to light the ontogeny of the individual, but also indicates its phylogenetic relationship in the general scheme of taxonomy. By means of the work presented in this thesis leading to the completion of the life history of Monoecocestus sigmodontis, it is hoped that some further contribution has been made to our knowledge of the Anoplocephalidae and their host-parasite relationship. In addition to developmental studies of this tapeworm, we have endeavored to uncover evidence of resistance to infection with this parasite on the part of the definitive host, the cotton rat, Sigmodon hispidus.
