What is an ecological principle behind the biological control method of managing with the insects?

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Biological Control**: Biological control is a method of managing pest populations using natural predators or parasites. This approach aims to reduce the reliance on chemical pesticides, promoting a more sustainable and environmentally friendly method of pest management.

2. **Ecological Principle**: The ecological principle behind biological control is **predation**. In this context, predation refers to the relationship where one organism (the predator) feeds on another organism (the prey).

3. **Role of Predators**: In biological control, specific insects or other organisms are introduced to target pest populations. These predators will capture and consume the pests, thereby helping to control their numbers.
