What does the term "pesticide resistance" refer to?

The term "pesticide resistance" specifically refers to the reduced effectiveness of a pesticide against a pest due to genetic changes in that pest population. Over time, as pests are exposed to a particular pesticide, some individuals may possess genetic traits that make them less susceptible or even immune to the effects of the chemical. These resistant pests can survive pesticide applications and reproduce, passing on their resistant traits to subsequent generations. This phenomenon can lead to the necessity of using higher doses of the pesticide, more toxic chemicals, or different pest management strategies to control the pest, as the original pesticide becomes less effective.

Understanding pesticide resistance is crucial for developing integrated pest management strategies and minimizing the risk of resistance development. Properly rotating pesticides and employing non-chemical control methods can help manage resistance and preserve the effectiveness of existing pest control options.
