How can resistant pests be managed effectively?

• A. Rotate pesticides with different modes of action
• B. Use the same pesticide continuously
• C. Increase the concentration of existing pesticides
• D. Avoid any pest management strategies

Answer: (A)

Managing resistant pests effectively involves utilizing strategies that minimize the likelihood of developing resistance. One of the most effective methods is to rotate pesticides with different modes of action. This strategy targets the pest population from multiple angles, which reduces the chances that pests will survive and adapt to a single method of control. When different modes of action are used, it creates a more challenging environment for pests, making it less likely that they will develop resistance. In contrast, using the same pesticide continuously can lead to increased resistance as pests become acclimated to its effects. Increasing the concentration of existing pesticides may temporarily reduce the pest population, but it does not address the core issue of resistance and can result in harmful environmental impacts and potential harm to non-target organisms. Avoiding any pest management strategies altogether would lead to unchecked pest populations, further exacerbating resistance issues. Implementing a plan that includes rotating pesticides is therefore essential in integrated pest management practices to maintain effectiveness over time.
