The correct term for when pest populations reach a level that necessitates control measures is known as a "Threshold." In the context of pest management, the threshold is a critical point that helps determine whether action should be taken to manage a pest population. This concept is integral for effective pest management strategies, as it balances the need to protect crops and the environment with the economic implications of pest control.

When the pest population exceeds the established threshold, it indicates that the potential for damage to the crops or ecosystem is significant enough to warrant intervention. This proactive approach helps prevent the escalation of pest issues, ensuring that control measures are implemented timely and effectively.

The other concepts, such as infestation, pest density, and action level, relate to pest management but do not specifically refer to the point at which action is required. Infestation generally denotes a high population of pests, while pest density refers to the number of pests per unit area. Action level may sometimes be used interchangeably with thresholds, but "Threshold" is the term that precisely defines the critical point for control measures.
