What role do pheromones play in pest control?

Pheromones are chemical signals used by insects and other animals for communication, particularly in mating and territory establishment. In pest control, pheromones can be effectively utilized as attractants in traps. This method capitalizes on the natural behaviors of pests, luring them into traps where they can be captured or exposed to control agents.

By using specific pheromones that mimic the natural scents of a pest's mating signals or food sources, pest control measures can be rendered more efficient. This technique not only targets specific pest species but also minimizes the impact on non-target organisms, making it a more environmentally friendly option compared to broad-spectrum pesticides.

While other options mention repelling pests, confusing populations, or enhancing resistance, those functions are not the primary roles of pheromones in pest control. Instead, the use of attractants allows for direct intervention in pest behavior, which can significantly reduce pest populations in a targeted manner.
