According to the material, which statement represents a principle of integrated pest management (IPM)?

• A. You can use toxic pesticides
• B. You must always avoid chemicals
• C. You should monitor pest levels and use evidence-based controls
• D. You should ignore pest population trends

Answer: (A)

IPM centers on monitoring pest populations and using a mix of control methods based on evidence of what works, with the goal of keeping pests at levels that don’t cause economic damage while minimizing risks to people, non-target organisms, and the environment. By routinely scouting and applying thresholds, you decide when intervention is needed rather than acting on a schedule or guesswork. Implementing IPM involves cultural controls (like sanitation and removing pest habitats), mechanical controls (traps and barriers), biological controls (natural enemies and biopesticides when appropriate), and, only if necessary, chemical controls that are selected for safety, effectiveness, and resistance management. The emphasis is on data-driven decisions and using treatments judiciously to achieve sustainable pest management.

Using toxic pesticides as a default isn’t consistent with IPM’s measured approach; IPM prioritizes monitoring and targeted, evidence-based options rather than blanket chemical use. Rigidly avoiding chemicals isn’t aligned with IPM either, since chemicals can be appropriate as part of a broader strategy when needed. Ignoring pest population trends would undermine the whole purpose of monitoring and data-driven decisions.
