“…However, it is also possible that the Lelystad strain never possessed this ability. Michel (1974) did an experiment in 1970 with a Weybridge strain of O. ostertagi which had approximately the same history as the present Lelystad strain, as it had been isolated from the field in 1957 and had been passaged indoors until it was brought to pasture in 1964. In contrast to the Lelystad strain, this strain showed inhibition of development as a result of environmental stimuli though the levels of inhibition were lower than in Glasgow and Weybridge field strains.…”

“…Following these early observations much research has been carried out on several aspects of inhibited development, particularly in Glasgow and Weybridge. Besides environmental stimuli the development of host resistance has been shown to be a factor in the aetiology of inhibited development (Michel, 1974). The results of these investigations have been summarized by Michel (1974Michel ( , 1978 and Armour (1978).…”

Summary :In order to confirm or refute the relay role of lagomorphs in the evolution of the Trichostrongylina (Nematoda), the following points were studied by summarizing previous works on the subject: the chronology of the life cycles (27 conducted in natural hosts, lagomorphs, ruminants or arvicolin rodents; 14 in experimental hosts); the parasitic phase in the experimental host and the adaptation involved; the migration of the parasites into the tissues of the host; the morphogenesis of larval stages and molecular phylogeny. These data confirm, in their entirety, that lagomorphs may be considered as "relay" hosts in the evolution of the Trichostrongylina. Résumé : LES LAGOMORPHES ONT-ILS JOUÉ UN RÔLE DANS

The life cycle of many endoparasites can be delayed by free-living infective stages and a developmental arrestment in the host referred to as hypobiosis. We investigated the effects of hypobiosis and its interaction with delay in the free-living stages on host-parasite population dynamics by expanding a previous attempt by Dobson & Hudson. When the parasite life cycle does not include free-living stages, hypobiosis destabilizes the host-parasite interactions, irrespective of the assumptions about the regulation of the host population dynamics. Interestingly, the destabilizing effect varies in a nonlinear way with the duration of hypobiosis, the maximal effect being expected for three to five months delay. When the parasite life cycle involves free-living stages, hypobiosis of short or intermediate duration increases the destabilizing effect of the first time delay. However, hypobiosis of a duration of five months or more can stabilize interactions, irrespective of the regulation of the host population dynamics. Overall, we confirmed that hypobiosis is an unusual time delay as it can stabilize a two-way interaction. Contrary to the previous conclusions, such an atypical effect does not require self-regulation of the host population, but instead depends on the existence of free-living stages.
