What role do pheromones play in pest management?

Pheromones play a significant role in pest management by serving as chemical signals that can influence the behavior of pests. One of the primary uses of pheromones in a pest management context is to disrupt mating cycles. By releasing synthetic pheromones that mimic the natural ones, pest managers can create confusion among target pest populations. Males can be distracted from finding females, leading to reduced mating success and subsequently lowering the pest population over time.

This method is particularly effective because it targets the specific species of concern without harming non-target organisms. It also integrates well with other pest management strategies since it is a form of biological control that minimizes chemical pesticide use.

The other options reflect misunderstandings of pheromone functions. For instance, while pheromones can indirectly affect beneficial insects by altering the dynamics of pest populations, their primary role is not to attract beneficial species. Additionally, promoting plant growth is unrelated to the function of pheromones, and stating that they have no role in pest management overlooks their effective applications in controlling pest populations through mating disruption.
