Pitfall traps are commonly known as interceptor traps due to their design and function in capturing insects. The concept behind pitfall traps involves creating a depression in the ground where insects inadvertently fall in, effectively capturing them as they traverse the landscape. This method allows researchers and pest control professionals to sample the population of insects that move across a specific area. The term "interceptor" reflects the trap's ability to intercept insects on their normal routes, making it an effective tool for monitoring insect populations. This method differs from other types of traps which rely on different attractant methods; for instance, pheromone traps attract insects with chemical lures, light traps attract nocturnal insects using light, and sticky traps capture insects on adhesive surfaces. Thus, the terminology of pitfall traps as interceptor traps is specifically tied to their function in intercepting insects rather than attracting them.
