What are the four basic steps or parts of IPM?

The four basic steps or parts of Integrated Pest Management (IPM) are inspection, assessment, action, and reinspection. This approach emphasizes a systematic process whereby the first step, inspection, involves identifying the presence and extent of pest problems. Following this, assessment allows the practitioner to evaluate the severity of the pest situation and determine the potential impacts on health and the environment.

The action phase is where specific control strategies are implemented based on the information gathered during inspection and assessment. These could include a mix of cultural, biological, and chemical controls tailored to the specific pest issue at hand. Finally, reinspection is crucial as it ensures that the strategies employed are effective and allows for adjustments to be made if necessary. This continuous cycle of evaluation and adaptation helps in maintaining control over pest populations while minimizing environmental impact and resistance development.

The other options, while they may contain elements relevant to IPM, do not accurately capture the comprehensive and procedural nature of the four basic steps as outlined in IPM principles.
