What does the term "pest resurgence" mean?

The term "pest resurgence" refers specifically to the re-emergence of pest populations after a control measure has been applied. This phenomenon can occur when the initial control methods, such as chemical treatments or biological controls, reduce the pest numbers significantly, but subsequently, the population rebounds, sometimes even surpassing the original levels. This can happen for various reasons, such as pests developing resistance to control measures, the removal of natural predators due to the treatment, or a competitive advantage gained by certain individuals in the pest population post-treatment.

Understanding pest resurgence is crucial for effective pest management, as it highlights the importance of integrating multiple strategies and not relying solely on one method. By recognizing the potential for resurgence, pest control practitioners can plan more sustainable and effective approaches to manage pest populations in ornamental and turf environments.
