What is one consequence of pesticide resistance in pest populations?

• A. Pests become more susceptible to control methods
• B. Increased costs for pest management
• C. Enhanced natural predation on affected pests
• D. A decrease in pest population size

Answer: (B)

One consequence of pesticide resistance in pest populations is increased costs for pest management. When pests develop resistance to certain pesticides, these control methods become less effective. As a result, pest control professionals must resort to using higher doses, more frequent treatments, or alternative chemical formulations, all of which can lead to higher expenses. Additionally, the need to incorporate diverse pest management strategies, such as integrated pest management (IPM), can further increase operational costs. This situation emphasizes the importance of monitoring and managing resistance to ensure effective pest control while minimizing economic impacts.
