Which practice is used to prevent pest movement between areas?

• A. Traps
• B. Sanitation
• C. Release of predators
• D. Quarantine

Answer: (D)

Preventing pest movement between areas relies on creating a boundary and controlling what can cross it. Quarantine does this by restricting and regulating the transport of plants, soil, equipment, and other materials from areas that may be infested to areas that are pest-free, often with inspections, permits, and requirements to clean or treat items before they cross the boundary. Traps and releasing predators target pests within an area or reduce their numbers but don’t establish a formal barrier to movement. Sanitation helps reduce harborages and food sources, lowering pest pressure, yet it doesn’t by itself stop pests from being carried to new areas. Releasing predators addresses pest populations but not the act of moving pests between locations.
