What is one of the known limitations of chemical pest control methods?

• A. They are always the first choice of action
• B. They can create resistance in pest populations
• C. They increase biodiversity
• D. They require minimal application effort

Answer: (B)

Chemical pest control methods have a known limitation in that they can lead to the development of resistance in pest populations. This phenomenon occurs when pests are exposed to specific chemicals over time, allowing those individuals that possess genetic traits for resistance to survive and reproduce. As a result, future generations of pests may not be effectively controlled by the same chemical, necessitating the use of stronger or different pesticides. This cycle tends to create a troubling scenario where more frequent applications or more potent chemicals are needed, which can increase costs, pose greater risks to non-target species, and contribute to environmental pollution. Understanding this limitation highlights the importance of integrating pest management strategies that are diverse, sustainable, and reduce dependence on chemical controls, such as cultural practices, biological control, and careful monitoring, to manage pest populations more effectively over the long term.
