What is a key pest?

A key pest is defined as a pest that typically causes significant damage to crops, plants, or ecosystems. This designation implies that the pest's presence can lead to economic losses or detrimental effects on agricultural productivity. Key pests often have a well-documented history of impact, making them a priority for management and control efforts to mitigate their effects.

In contrast, pests that cause sporadic problems do not consistently threaten crop health or yield, while those that are only a concern in certain seasons may not warrant year-round management strategies. Pests that do not require management measures are usually of little concern and may not result in significant damage, thereby not qualifying as key pests. Understanding the impact and management needs of key pests is essential for effective pest management strategies in agriculture.
