What is one effect of using non-target organisms in biological pest control?

• A. They can enhance pest outbreaks
• B. They are beneficial and usually harmless to the environment
• C. They can disrupt the ecological balance
• D. They help in reducing costs of pest management

Answer: (C)

Using non-target organisms in biological pest control can disrupt the ecological balance by causing unintended consequences within the ecosystem. When non-target species are affected—whether harmed, outcompeted, or displaced by the introduced biological control agents—the established predator-prey relationships and community dynamics can be altered. This disruption may lead to an increase in certain pests if their natural enemies are eliminated, or it may facilitate the establishment of new, potentially invasive species, further jeopardizing the local biodiversity. Maintaining ecological balance is essential for sustainable pest management. Therefore, while biological control aims to reduce pest populations, careful consideration must be given to the potential impacts on non-target organisms, as the consequences can ripple throughout the ecosystem.
