What is the Economic Threshold or Action Threshold?

The Economic Threshold, also known as the Action Threshold, refers specifically to the pest population density at which control measures should be implemented to prevent reaching the Economic Injury Level (EIL). The EIL is the point at which the cost of pest damage equals the cost of pest management. Therefore, by determining the Economic Threshold, pest managers can act before the situation worsens, thereby avoiding economic loss.

This concept is crucial in integrated pest management (IPM) because it allows for timely interventions that are cost-effective and environmentally responsible. When pest levels reach this threshold, it signals the need for action to prevent further economic detriment, illustrating a proactive approach in agricultural pest management.
