What does "pesticide resistance" refer to?

Pesticide resistance refers to the ability of pests to survive exposure to pesticides that would typically be lethal to the majority of the population. This phenomenon occurs when certain individuals within a pest population possess genetic traits that enable them to withstand the effects of a pesticide. Over time, as these resistant individuals reproduce, they pass on their resistance to subsequent generations, leading to a population that is predominantly resistant to that pesticide.

Understanding pesticide resistance is crucial for effective pest management. It emphasizes the importance of implementing integrated pest management strategies, such as rotating different classes of pesticides and using alternative control methods, to prevent or mitigate resistance development. The correct answer highlights the significant challenge that resistance poses to pest control efforts and the need for ongoing adaptation in management practices.
