Which of the following methods is included in pest monitoring?

Regular inspection is a fundamental method in pest monitoring because it involves systematically checking the environment, plants, and structures for signs of pest activity. This proactive approach allows for early detection of pest problems, which is crucial for effective management and control. By observing pest behavior and populations through inspections, pest management professionals can make informed decisions regarding the need for interventions, thus optimizing resource use and minimizing unnecessary pesticide application.

In contrast, increasing pesticide usage, introducing predators, and planting pest-resistant crops are all methods related to pest control or management, rather than monitoring. While they may contribute to an overall pest management strategy, they do not involve the systematic observation and assessment that characterizes effective pest monitoring. Regular inspections focus on assessing and tracking pest populations over time, which is essential for adjusting control measures promptly.
