What is a secondary pest?

• A. A pest that is always harmful to crops
• B. A pest that becomes a problem when key pests are controlled
• C. A type of beneficial insect that controls other pests
• D. A pest that is naturally resilient to pesticides

Answer: (B)

A secondary pest refers to a pest that does not typically pose a significant threat to crops under normal circumstances but can become problematic when the populations of key pests are managed or reduced through control measures. When the primary pests are suppressed, secondary pests might take advantage of the less competitive environment, potentially leading to increased populations and subsequent damage to crops. Understanding this concept is crucial in pest management strategies, as it highlights the importance of monitoring and managing pest populations holistically. This prevents situations where the control of one pest inadvertently leads to the proliferation of another, which can result in further crop damage and increased management costs. In essence, even though secondary pests may not have been a concern initially, proper pest management must consider their potential to become problematic once primary pest pressures are alleviated.
