Which is a commonly used method for pest monitoring in IPM?

The commonly used method for pest monitoring in Integrated Pest Management (IPM) is the use of traps and sampling. This approach allows pest management professionals to collect data on pest populations, species presence, and population dynamics over time. By employing various types of traps—such as sticky traps, pheromone traps, or pitfall traps—monitoring can help determine the extent of a pest problem and inform subsequent management decisions.

Sampling is crucial because it provides quantitative data that guides the timing and methods of control measures. Monitoring can reveal trends and changes in pest populations that may not be immediately visible, thus enabling more timely and targeted interventions. This step is vital in the IPM process, as it encourages a thoughtful and informed approach to pest management, allowing for the effective use of resources and minimization of pesticide usage.

In contrast, soil fumigation, thermal treatment, and crop selection are more about pest control or prevention rather than ongoing monitoring. Soil fumigation and thermal treatment are intervention strategies aimed at eliminating pests or pathogens from the environment, while crop selection pertains to choosing pest-resistant varieties as a preventive measure. While all these strategies may play a role in IPM, they do not focus on the essential component of monitoring which is accomplished primarily through traps and sampling.
