Ap Envirormental -5.6 - Pest Control Methods

What is integrated pest management (IPM)?

A pest control strategy that uses a combination of techniques to minimize environmental impact, including biological, chemical, and physical methods.

What is the goal of integrated pest management (IPM)?

To reduce pest damage to economically acceptable levels while minimizing harm to the environment and non-target organisms.

What are biological pest control methods?

Using natural predators, parasites, or pathogens to control pest populations (e.g., ladybugs eating aphids).

What are chemical pest control methods?

Using pesticides like insecticides, herbicides, or fungicides to kill pests.

What are the environmental consequences of chemical pesticides?

1. Development of pesticide-resistant pests.

2. Bioaccumulation and biomagnification in the food chain.

3. Contamination of soil and water.

What is crop rotation, and how does it help control pests?

Changing the type of crop grown in a field each season to disrupt pest life cycles and prevent soil depletion.

What are genetically modified organisms (GMOs) in pest control?

Crops modified to resist pests or produce their own pesticide (e.g., Bt corn).

What are physical pest control methods?

Manual removal, barriers (like nets), or traps to manage pest populations.

What is the downside of monocropping in pest management?

It creates a habitat for pests to thrive, increasing reliance on pesticides.

Why is pest resistance a problem?

Pests adapt to chemical pesticides over time, making them less effective and requiring stronger or alternative solutions.

How does IPM benefit the environment?

It reduces the need for chemical pesticides, protects non-target species, and promotes sustainable farming practices.
