A Conceptual Model for Assessing the Minimum Size Area for an Area-Wide Integrated Pest Management Program

Figure 1

Schematic diagram of the expected changes in pest density from an infested area (high pest pressure), through the buffer zone (𝐵), into the core area (𝐴) in the case of an eradication strategy. In the rolling-carpet approach, declines in pest density represent declines over time, although the form of the slope is schematic.
