Insect pheromones are critical components of pest monitoring and control technologies used to combat pests that attack crops. Using pheromones to manage pests indirectly, such as mating disruption, mass trapping, attract-and-kill, and push-pull, are some of the most effective methods of direct pest control. The aggregation pheromones generated by weevil pests are produced by males to attract both males and females, and as a result, they are referred to as aggregation pheromones. The chemical makeup of these insect pheromones is given below for many different weevil species. Weevil aggregation pheromones frequently contain several components, and the presence of host-plant volatiles can enhance the effectiveness of these pheromones.
