Which statement defines mechanical control?

Which statement defines mechanical control?

• A. It uses a device such as a trap or barrier
• B. It uses biological agents
• C. It uses genetic modification
• D. It relies on environmental changes only

Answer: (A)

Mechanical control relies on physical means to reduce pest pressure. Using a trap or barrier directly interacts with the pest or blocks its access, which is the essence of this approach. This is different from introducing living organisms to attack pests (biological control), altering the pest’s genetics (genetic modification), or relying only on changing environmental conditions to reduce pests (cultural or environmental controls). Examples include sticky traps, traps that capture pests, or barriers like nets or fences that physically prevent pests from reaching the turf.
