What is the pest resurgence phenomenon?

The pest resurgence phenomenon refers to the increase in pest populations that can occur following the removal of natural predators. When natural predators or biological control agents are eliminated, often through the excessive use of pesticides, pest populations can rebound rapidly. This is because the predators that would normally keep the pest population in check are no longer present, allowing pests to reproduce unchecked.

In addition to this, the application of pesticides can sometimes target not only the pests but also their natural enemies. This leads to a situation where, once the pesticide wears off, the pest population can increase dramatically due to the absence of these natural control mechanisms. This cycle can create a reliance on chemical controls, potentially creating ongoing issues with pest management in agriculture.

Other options illustrate different concepts unrelated to the specific dynamics of pest resurgence. For instance, some focus on the immediate effects of pesticide use or stabilization, neither of which captures the underlying mechanism of pest population increases tied to predator removal.
