What is the primary reason for using biological pest control?

The primary reason for using biological pest control is to introduce beneficial organisms that suppress pest populations. This method is centered around utilizing natural predators, parasites, or pathogens to target specific pests without causing harm to the environment or non-target species. By promoting the presence of these beneficial organisms, it creates a more balanced ecosystem and can effectively manage pest populations over time.

While reducing the need for chemical treatments is an important aspect and benefit of biological control, it is not the primary reason. The focus is specifically on enhancing natural means of pest population suppression. Additionally, the goal is not to eliminate all pests, as some pests may play a role in the ecosystem, and increasing soil fertility pertains to another aspect of agricultural practices that is separate from pest management.
