  • Title: Host suppression and stability in a parasitoid-host system: experimental demonstration.
    Author: Murdoch W, Briggs CJ, Swarbrick S.
    Journal: Science; 2005 Jul 22; 309(5734):610-3. PubMed ID: 16040706.
    Abstract:
    We elucidate the mechanisms causing stability and severe resource suppression in a consumer-resource system. The consumer, the parasitoid Aphytis, rapidly controlled an experimentally induced outbreak of the resource, California red scale, an agricultural pest, and imposed a low, stable pest equilibrium. The results are well predicted by a mechanistic, independently parameterized model. The key mechanisms are widespread in nature: an invulnerable adult stage in the resource population and rapid consumer development. Stability in this biologically nondiverse agricultural system is a property of the local interaction between these two species, not of spatial processes or of the larger ecological community.
