What term describes the pest population density that causes losses equal to the cost of control measures?

The concept that describes the pest population density resulting in losses that equal the cost of control measures is known as the economic injury level. This term reflects the point at which the financial losses caused by the pest infestations can be effectively addressed through the application of control measures, meaning that the cost of control is balanced by the potential economic loss caused by the pest. It serves as a critical threshold for making decisions about pest management; if the pest population exceeds this level, intervention is economically justified.

Understanding the economic injury level assists pesticide applicators and farmers in making informed decisions about when to initiate control measures, thus optimizing resources and preventing unnecessary expenditures.
