Abstract

Temporal density-dependent parasitism appears to explain the development of some pest- and pathogen-suppressive soils. In many examples, anenrichment of hosts (soil-borne pests or pathogens) precedes and supports a build up of beneficial parasites in perennial crops or in monocultures, and the population dynamics of hosts and parasites may be described in epidemiological terms. Although the examples support the concept of a balance of nature based on density-dependent regulation, we lack detailed understanding of the processes that drive these beneficial epidemics. In addition, the epidemics develop slowly and often do not provide the control expected by farmers. Current research, therefore, emphasizes inundative release of beneficial agents. Nevertheless, we should study epidemics in soil in order to learn how they might be enhanced, to learn how better to utilize inoculum that is inundatively added to soil; and to contribute to the general discussion of population biology and regulation.
