What are types of pesticide resistance?

Pesticide resistance can be classified into several types, including metabolic resistance, where pests develop enzymes to break down chemicals; target-site resistance, where changes occur in the pest's biological targets of the pesticide; and behavioral resistance, where pests alter their habits to avoid exposure. Additionally, cross-resistance can occur when a pest resistant to one pesticide also shows resistance to related chemicals. These mechanisms can significantly reduce the effectiveness of pest control measures over time.
