What is the main goal of using pheromone traps in IPM?

The primary goal of using pheromone traps in Integrated Pest Management (IPM) is to attract pests for monitoring and control. Pheromone traps utilize specific chemical signals (pheromones) released by insects to lure them into the trap. This method serves two key purposes: it allows for the detection and identification of pests in the environment and helps in assessing pest populations over time.

By monitoring pest populations through these traps, growers can make informed decisions regarding pest management strategies. For instance, if trap captures indicate that pest levels are rising, appropriate measures such as introducing biological controls or applying pesticides selectively can be implemented. This targeted approach helps manage pest populations effectively while minimizing the impact on beneficial organisms and the environment.

The other options, while related to pest management, do not capture the primary use of pheromone traps. Eliminating pests completely is not typically realistic or sustainable in IPM; increasing crop yield is more of an indirect benefit derived from effective pest control; and replacing chemical pesticides is not an explicit aim of using pheromone traps, which are utilized to complement existing pest management practices rather than completely take over.
