What is a trap crop?

• A. A crop that is never harvested
• B. A crop planted to attract pests away from the main crop, reducing damage
• C. A crop that does not require any pest management
• D. A population of crops planted to increase pest resistance

Answer: (B)

A trap crop is defined as a crop specifically planted to draw pests away from the main crop, thereby reducing the damage those pests may cause to the primary agricultural product. This strategy is often implemented in integrated pest management systems as a means of controlling pest populations more effectively while minimizing the dependence on chemical pesticides. By using a trap crop, farmers can lure pests in a controlled manner, often choosing a plant that is more attractive to the pests than the main crop. Once the pests are concentrated on the trap crop, they can be managed (through physical removal, targeted pesticides, or natural predators) without impacting the primary crop. This technique not only helps protect the main crop but can also enhance overall ecosystem health by promoting biodiversity. The other choices describe concepts that do not align with the definition of a trap crop. For example, a crop that is never harvested does not interact with pest management strategies, and a crop that requires no pest management overlooks the complexities of agricultural ecosystems. Similarly, while improving pest resistance is vital, a population of crops aimed solely at resistance does not serve the specific role of attracting pests away from a main crop.
