What is resistance in pests?

Resistance in pests refers to their ability to withstand or survive treatments that were previously effective against them. This phenomenon occurs when individuals in a pest population develop or acquire traits that enable them to survive applications of chemical controls, such as pesticides, that would normally kill them. Over time, as these surviving individuals reproduce, they pass on their resistance traits to future generations. This can lead to a population of pests that are largely unaffected by the same application or treatment, which can significantly complicate pest management efforts.

This understanding is crucial for effective Integrated Pest Management (IPM), as it emphasizes the need for monitoring pest populations and considering resistance management strategies. Effective pest management may require rotating the types of pesticides used, employing non-chemical control methods, and implementing strategies that minimize pest exposure to potentially effective treatments to avoid the development of resistance.
