Which control method directly eliminates a pest?

Mechanical control directly eliminates a pest through physical means. This method includes actions such as trapping, hand-picking, or using devices that kill pests, ensuring that the targeted organisms are removed from the environment. For instance, hand-picking caterpillars from plants or using insect vacuums to collect insects are practical examples of mechanical control.

In contrast, cultural control focuses on altering farming practices to make the environment less conducive to pest infestations. This might include crop rotation or adjusting planting dates but does not involve the direct elimination of pests.

Biological control involves the use of natural predators or parasites to manage pest populations. While effective, this method relies on the interactions within the ecosystem rather than directly removing the pests through immediate action.

Integrated Pest Management (IPM) is a comprehensive approach that combines multiple strategies for pest control, including cultural, mechanical, and biological methods. While IPM promotes a balanced ecosystem and helps manage pest populations effectively, it does not specifically indicate the direct elimination of pests through one singular method.

Thus, mechanical control is characterized by its immediate impact on pest populations, which distinctly sets it apart from the other methods described.
