What is pesticide resistance?

Pesticide resistance is defined as a phenomenon where pests become less affected by a pesticide. This occurs when a population of pests evolves over time to withstand the effects of a specific pesticide, often due to selective pressure from repeated applications. When pests that possess genetic traits allowing them to survive pesticide treatment reproduce, the resulting population increasingly consists of individuals that are resistant to that pesticide. This can lead to reduced efficacy of the pesticide and necessitate the use of alternative strategies or products to manage the pest effectively.

Understanding pesticide resistance is crucial for pest management, as it impacts the long-term sustainability of pest control strategies. Continuous reliance on a single pesticide can accelerate the development of resistance, highlighting the need for integrated pest management approaches that include rotation of pesticides, diverse control methods, and monitoring pest populations.
