In pest management, which is considered a mechanical control measure?

• A. Biological pest introduction
• B. Pesticide spraying
• C. Physical barriers like traps or screens
• D. Attracting natural predators

Answer: (C)

Mechanical control measures in pest management involve the use of physical methods to control pest populations without the use of chemical agents. The correct choice identifies physical barriers such as traps or screens as a fundamental aspect of mechanical control. These methods work by physically preventing pests from accessing certain areas, capturing them, or eliminating them through non-chemical means, which can effectively reduce pest numbers without introducing chemicals into the environment. The other options reflect different pest control strategies. Biological pest introduction entails releasing natural predators or parasites to control pest populations, which is a form of biological control. Pesticide spraying involves applying chemicals to eliminate or manage pests, representing a chemical control method. Attracting natural predators is also considered a biological control strategy, as it depends on enhancing the ecosystem to favor natural enemies of pests. Each of these practices plays a role in integrated pest management, but they do not fall under mechanical control measures.
