Present theory states that in species-poor assemblages interactions among species are negligible and assemblage structure is a result of host/parasite interactions. A corollary to this theory is that parasite species assemblages should behave as accumulations of multiple-kind items drawn from a population in which only the relative probability of drawing each kind varies. This study was designed to test this prediction by comparing descriptor values, including diversity indices, species density values, equitability, and prevalence to those obtained from data produced by a Monte Carlo simulation model. The parasite assemblage consisted of 7 parasite species or types found in the fathead …

Parasite species assemblages currently are thought to range from isolationist to interactive, their dynamic properties being related to the number of species and types of hosts involved. The literature contains few experimental tests of this concept, however, and many of the host/parasite systems studied to date are not amenable to experimental manipulation. In this review, the presence of a parasite species, in a sample of host individuals, is considered to be an evolutionary phenomenon, but the parasite's population structure is considered to be an ecological one. Studies that allow evaluation of these two influences are comparative in nature and include …
Host Stadium Specificity In The Gregarine Assemblage Parasitizing Tenebrio Molitor, Richard E. Clopton, John J. Janovy Jr., Tamara J. Percival Cook
Host Stadium Specificity In The Gregarine Assemblage Parasitizing Tenebrio Molitor, Richard E. Clopton, John J. Janovy Jr., Tamara J. Percival Cook

Reciprocal cross-stadia experimental infections were used to demonstrate stadium specificity within the gregarine assemblage parasitizing Tenebrio molitor, the yellow mealworm. Gregarina cuneata, Gregarina polymorpha, and Gregarina steini are characteristic parasites of larval T. molitor. Gregarina niphandrodes is a characteristic parasite of adult T. molitor. Experimental infections were produced in all homologous host-parasite combinations. No infection was produced in heterologous or cross-stadia combinations. This study introduces the concept of separate, distinct parasite niches corresponding to separate life cycle stages and established by known, predictable life cycle events within a single host species.
