What are pheromone traps used for in pest management?

Pheromone traps play a crucial role in integrated pest management by monitoring and managing pest populations. They utilize specific chemical signals called pheromones, which are emitted by pests to attract mates. By placing these traps in the field, farmers and pest management professionals can capture adult pests. This not only helps in assessing the presence of the pest but also provides valuable information regarding population dynamics, including the timing of pest life cycles and potential outbreaks.

Monitoring pest populations through pheromone traps allows for more informed decision-making regarding pest control strategies. For example, if trap counts indicate a rising pest population, this may prompt timely interventions such as targeted insecticide applications or the implementation of biological control measures. This proactive approach can minimize crop damage, reduce the need for broad-spectrum pesticides, and ultimately lead to more sustainable agricultural practices.

In contrast, options related to repelling pests, enhancing soil fertility, or tracking weather patterns do not align with the primary function of pheromone traps, which is focused on surveillance and management of pest pressures rather than repulsion or environmental factors.
