What does biological control focus on?

Biological control focuses on protecting and adding natural enemies of pests. This method involves using the natural predators, parasites, or pathogens of pests to manage and suppress pest populations. By introducing or enhancing the populations of these natural enemies, biological control seeks to create a balanced ecosystem where pest populations are kept in check without the use of synthetic chemicals.

This approach is rooted in the understanding that ecosystems have inherent checks and balances, and by leveraging these natural relationships, pest control can be achieved in a more environmentally friendly manner. For instance, releasing ladybugs to control aphid populations or utilizing parasitoid wasps that specifically target certain pests are practical applications of biological control.

The other choices, while they represent legitimate pest control methods, do not align with the principles of biological control. Traps and vacuuming methods are physical control measures, excluding pests focuses on prevention, and applying synthetic chemicals pertains to chemical control strategies. These approaches differ significantly from the biological methods that emphasize ecosystem management and the role of natural pest enemies.
