Biological Control of Pests — NEET Biology
📚 Practice ConceptBiological control of pests and diseases: In agriculture, there is a method of controlling pests that relies on natural predation rather than introduced chemicals. A key belief of the organic farmer is that biodiversity furthers health. The more variety a landscape has, the more sustainable it is. The organic farmer, therefore, works to create a system where the insects that are sometimes called pests are not eradicated, but instead are kept at manageable levels by a complex system of checks and balances within a living and vibrant ecosystem. Contrary to the 'conventional' farming practices which often use chemical methods to kill both useful
Which of the following statements regarding the importance and approach of biocontrol methods are NOT correct? S1: Biocontrol methods are increasingly favored because they are often more cost-effective and faster acting than synthetic pesticides. S2: Organic farming emphasizes a holistic approach to pest management, aiming to maintain biodiversity rather than pest eradication. S3: Synthetic pesticides typically offer specific targeting of pests, minimizing harm to beneficial organisms in an ecosystem. S4: The reliance on chemical methods in conventional farming can lead to pollution of soil, groundwater, and crop plants. S5: Understanding the life cycles and feeding patterns of both pests and predators is crucial for developing effective biocontrol strategies. S6: Biocontrol measures aim to completely eliminate pest populations to ensure maximum crop yield.
