The trap crop concentrates pests in one location where they can be removed, killed, or treated, reducing pest pressure on the target crops. This is a specific application within integrated pest management — using the pest&rsquo;s own behavior against it.</p> <h2 id="mechanism">Mechanism</h2> <p>Trap crops work because specialist pests preferentially colonize plants they have evolved to feed on. A pest insect navigates its environment using volatile chemical signals released by its host plants. When a trap crop emits stronger signals than nearby target crops, or is chemically more attractive than the target, the pest preferentially lays eggs on the trap crop.</p>
