What does the term "pest resurgence" refer to?

The term "pest resurgence" specifically refers to the phenomenon where pest populations increase significantly after they have been reduced or controlled through various means. This rebound often occurs because the control measures may not have addressed the underlying factors that allow the pest population to thrive, such as habitat preservation, resistance to the control methods, or the absence of natural predators.

When a pest population is controlled, it can trigger an ecological response that allows the pests to reproduce quickly, leading to a scenario where their numbers rebound to previous or even greater levels. This cycle can create challenges for pest management, as the resurgence can diminish the effectiveness of the control measures intended to keep pest populations in check. Understanding pest resurgence is crucial for developing sustainable pest management strategies that consider both immediate control and long-term ecological balance.
