Area wide management DEFINITION - systematic pest control uniformly applied to the total population

Area wide management DEFINITION - systematic pest control uniformly applied to the total population of a key pest in a clearly defined geographical area to predetermined levels using biologically based criteria (Bloem 2017) DEFINITION – management of a pest across a well defined area, using a suite of available tools, targeting all pest habitats and requiring coordination and cooperation On-farm and off-farm

Key characteristics • Monitoring • Knowledge of pest • Defined area • Total population

Key characteristics • Monitoring • Knowledge of pest • Defined area • Total population (hosts and habitats) • Multiple stakeholders • Proactive • Reducing Re-entry Can these be applied to management of an area?

Key characteristics • Monitoring – early detection • Know your pest – ID? •

Key characteristics • Monitoring – early detection • Know your pest – ID? • Protected defined area • Hosts and habitats – where could it be? • Multiple stakeholders – who? • Proactive – before there’s a problem • Reducing Re-entry, or preventing entry Be prepared – eradicate?

Strategic Options of Insect Pest Control (AW-IPM) • Suppression: Reducing insecticide use and crop losses, and facilitation of sustainable agriculture • Containment: Avoiding the spread of an insect pests • Eradication: Developing areas free of major disease vectors or facilitation of international trade • Prevention: Avoiding establishment of invasive exotic pests
