War Against Pests

Comments (0)

From CIEC Promoting Science, these materials help students to understand key ideas in the use of agrochemicals. These include:
• synthetic and natural pesticides
• biological control
• food chains and the management of ecosystems
• predator-prey relationships
• benefits and drawbacks of using agrochemicals
• human population and food requirements

To achieve this, students undertake a series of activities that include:
• A data interpretation exercise, based on the effect of garlic on fruit flies, which introduces the concept of natural pesticides
• Study of alternative and complementary methods of pest control, their effectiveness and dangers
• Pest control and predator-prey relationships
• Role play exercise based on an expert panel question and answer format.
