What is the term for a predetermined level of pest infestation or damage warranting pest management action?

The term for a predetermined level of pest infestation or damage that triggers the need for pest management action is known as an action threshold. This concept is critical in integrated pest management (IPM), as it helps determine when control measures should be implemented. The action threshold is not just an arbitrary number; it is based on various factors, including economic, environmental, and aesthetic considerations, allowing for timely intervention before pest populations cause significant harm.

Understanding this concept is essential for pest management professionals, as it enables them to make informed decisions about when to apply pesticides or implement alternative control methods. By adhering to action thresholds, applicators can effectively manage pests while minimizing unnecessary pesticide use, thus promoting more sustainable practices.
