What is the main purpose of using a trap crop in pest management?

• A. To attract pests away from the main crop
• B. To increase pollination
• C. To improve drought tolerance
• D. To reduce nutrient needs

Answer: (A)

Trap crops are used to lure pest insects away from the main crop by offering a more attractive host plant. By drawing pests to the trap crop, you concentrate damage where it’s easier to monitor, spray, or remove, which protects the valuable crop and supports overall pest management. For example, placing a highly attractive plant near or around the main crop can pull pests like caterpillars or beetles onto the trap, making it simpler to control them without spraying the entire field. This tactic is about managing pest pressure, not improving pollination, drought tolerance, or nutrient uptake, which is why attracting pests away from the main crop is the primary purpose.
