What is an example of a monitoring technique used in pest management?

Pheromone traps are designed to attract and capture specific pests using chemical signals that these insects naturally use to communicate. This monitoring technique is highly effective for detecting the presence of certain pest species, helping pest management professionals to assess pest populations and make informed decisions about the need for control measures.

Using pheromone traps allows for early detection of infestations, which is crucial for managing pest populations before they become too problematic. By monitoring the activity levels and patterns of the pests captured in these traps, practitioners can tailor their management strategies to target the specific life stages or species present, optimizing the control efforts.

In contrast, the other methods listed, such as vacuuming, dusting, and spraying chemicals, are primarily control techniques rather than monitoring strategies. They are used to physically remove pests or apply pesticides to manage pest populations rather than providing information about their presence or activity levels.
