What is the purpose of trap crops in integrated pest management (IPM)?

The purpose of trap crops in integrated pest management (IPM) is primarily to attract pests away from the main crop, which helps to reduce overall pest levels. Trap crops are chosen for their ability to lure specific pests away from the crops that are more valuable or sensitive. By concentrating pests on these plants, growers can more effectively manage pest populations, potentially reducing the need for chemical controls and minimizing damage to the primary crops. This tactic not only helps to protect the main crops but also promotes a more sustainable agricultural approach by utilizing the natural behavior of insects to manage pest populations.

The effectiveness of trap crops hinges on selecting the right species that are attractive to the target pests, ensuring that they can divert enough pests away from the economically important crops. This strategy is particularly effective when combined with other IPM practices, leading to better pest management outcomes and healthier crop production.
