How can trap crops be used in pest management?

Trap crops play a crucial role in pest management by utilizing the behavior of pests to lure them away from the primary crops. When a specific crop is planted that is more attractive to pests than the main crop, it draws the pests towards itself. This strategic planting helps to reduce damage to the primary crops, as the pests focus on the trap crop instead.

By effectively using trap crops, farmers can safeguard their main crop from pest infestations, which can lead to less need for chemical pesticides and more sustainable agricultural practices. This method capitalizes on the natural tendencies of pests, making it an effective tool in an integrated pest management plan.

The other options do not accurately represent the function of trap crops in pest management. Enhancing soil quality, planting only native species, or increasing the use of fertilizers does not specifically address the technique of diverting pests from main crops, which is the core idea behind utilizing trap crops in agriculture.
