What does 'pest resurgence' refer to?

'Pest resurgence' specifically refers to the rebound of pest populations, particularly in scenarios where control measures, such as pesticides, have been applied. This phenomenon often occurs when some pests develop resistance to the control methods implemented, allowing them to thrive despite efforts to manage or reduce their populations. When resistant individuals survive the treatment, they reproduce, leading to an increase in the population of pests that are harder to control.

This concept highlights the importance of integrated pest management, which seeks to minimize the risk of pest resurgence by employing a variety of approaches rather than relying solely on pesticides. Understanding the dynamics of pest resurgence is critical for pest management strategies, as it can affect the long-term sustainability of pest control methods.
