What is the primary goal of the classical approach in biological control?

The primary goal of the classical approach in biological control is to establish self-sustaining populations of natural enemies. This method relies on introducing a specific predator, parasite, or disease that targets invasive or unwanted species within an ecosystem. By establishing these natural enemies, the approach aims to create a balance in the ecosystem, allowing the natural enemies to thrive and control the pest population over the long term without the need for constant human intervention.

This strategy distinguishes itself from methods that involve complete eradication or extensive chemical applications, which may lead to unintended environmental impacts or the disruption of native species. By promoting self-sustaining populations, the classical approach supports a more sustainable and ecologically sound management of invasive species, ensuring that the control measure remains effective even after initial efforts cease.
