What is biological control in pest management?
Using chemical substances to eliminate pests
Introduction of natural enemies to control pests
Control of pests through physical means
Elimination of pests through cultural practices
The correct answer is: Introduction of natural enemies to control pests
Biological control in pest management is the use of natural enemies such as predators, parasites, and pathogens to regulate pest populations. This method is considered to be environmentally friendly and sustainable compared to options such as using chemicals or physical means, which can have negative impacts on the ecosystem. Cultural practices, such as crop rotation and sanitation, can also help manage pest populations but they do not involve the introduction of natural enemies. Therefore, option B is the most appropriate and effective method for controlling pests without causing harm to the environment.
