Which of the following is not one of the pest management approaches described?

• A. Eradication
• B. Prevention
• C. Suppression
• D. Containment

Answer: (D)

Pest management relies on clear aims: removing the pest from an area entirely, preventing its entry or further spread, or lowering its numbers to a level where it no longer causes economic or health harm. Eradication is the approach that means eliminating the pest from a defined area. Prevention focuses on stopping pests from getting in or establishing in a location. Suppression aims to bring pest populations down to an acceptable level, though not necessarily to zero.

Containment isn’t described here as its own separate primary approach. While keeping a pest from spreading can be part of other strategies, this material treats containment as not a distinct primary approach, which is why it’s the choice that doesn’t fit with the described set.
