What are the four components of Integrated Pest Management (IPM) in aquatic pest control?

• A. Biological, cultural, mechanical, and chemical methods.
• B. Chemical methods only.
• C. Biological control only.
• D. Mechanical removal only.

Answer: (A)

IPM in aquatic pest control relies on using a balanced mix of strategies to prevent and manage pests with minimal harm to the environment. The four components are biological control, which leverages natural enemies such as predators, parasites, or diseases to suppress pests; cultural methods, which modify the environment and practices to reduce pest establishment and reproduction, like managing nutrient inputs, water depth and flow, and seasonal timing to disrupt life cycles; mechanical or physical methods, including removing pests by hand or with equipment, using barriers or nets, or physically altering habitat to make it less hospitable; and chemical methods, which involve pesticides used only when necessary and in a targeted, judicious way, selecting aquatic-specific products, following labels, and rotating chemistries to reduce resistance. By integrating these approaches and monitoring pest levels, you achieve effective control while protecting water quality.
