There are four main terms with similar yet unique definitions to consider when developing a method of pest management. Eradication is the application of phytosanitary measures to eliminate a pest from an area or geographic region (Food and Agriculture Organization, 2005). Suppression involves maintaining an insect population at or below the economic injury level (Pfadt, 1972; Hendrichs et al., 2002). Containment is the application of phytosanitary measures in and around an infested area to prevent spread of a pest (FAO, 2005). Prevention is the application of phytosanitary measures in and/or around a pest free area to avoid the introduction of a pest. Of the four, only prevention involves a preemptive strategy to keep the pest at bay rather than managing it upon arrival (Hendrichs et al., 2002, 2005; Food and Agriculture Organization, 2005). The other three terms, eradication, suppression and containment, are designed to manage a pest after its initial infestation. These terms are not mutually exclusive; rather, they provide different strategies and tactics designed to custom fit an areawide IPM (AW-IPM) program. The section of this chapter on pink bollworm (Pectinophora gossypiella) provides a brief review of San Joaquin Valley, California in regards to prevention, as well as the ongoing efforts to eradicate this invasive lepidopteran insect from the cotton growing regions of the southwest USA and northern Mexico. The section on Mediterranean fruit fly (Ceratitis capitata) of this chapter discusses in greater detail the economic viability and opportunity cost of eradication versus suppression in the international market.
