Which type of control method relies on the use of pheromones?

Pheromones are chemical substances produced by insects that can affect the behavior of other individuals of the same species. In biological control, the use of pheromones is significant because they can help manage pest populations naturally. This method may involve using synthetic versions of these natural chemicals to disrupt mating patterns, lure pests to traps, or even induce responses that lead to population reductions. By harnessing the natural communication systems of pests, biological control strategies can provide effective pest management solutions that minimize reliance on more harmful chemical treatments.

In contrast, other control methods like mechanical control involve physical means to eliminate pests, cultural control focuses on modifying agricultural practices to reduce pest habitats, and chemical control typically relies on pesticides to manage pest populations. These methods do not utilize pheromones in the same strategic manner as biological control does, which highlights the unique role pheromones play in pest management strategies under the biological control umbrella.
