Name a method of mechanical control in pest management.

• A. Aerial spraying of pesticides
• B. Traps, barriers, and hand-picking
• C. Soil fumigation
• D. Using genetically modified organisms

Answer: (B)

Mechanical control in pest management refers to methods that physically disrupt pests and their activities without the use of chemical agents. The correct answer encompasses techniques such as traps, barriers, and hand-picking, all of which work by physically removing pests or preventing their access to crops or sensitive areas.

Traps are instruments designed to capture pests, helping to reduce their population or monitor their presence. Barriers, like row covers or fencing, prevent pests from reaching valuable plants. Hand-picking is a direct method where individuals manually remove pests from plants, which is effective for larger insects or those that can be spotted easily.

These approaches are environmentally friendly and can be an integral part of an integrated pest management strategy, allowing for the protection of crops while minimizing harm to non-target organisms and the ecosystem.
