Step 1
What is meant by the term biological control?
Answer
Biological control refers to the method of managing pest populations by utilizing natural predators, parasites, or infectious agents that reduce pest numbers. This approach aims to minimize reliance on chemical pesticides, promote ecological balance, and maintain agricultural sustainability. It leverages the natural interactions in ecosystems where certain organisms help regulate or eliminate the populations of harmful pests.
Step 2
Give an example of biological control in agriculture.

An example of biological control in agriculture is the introduction of ladybirds to manage aphid populations. Ladybirds prey on aphids, effectively reducing their numbers and minimizing crop damage. Other examples include using parasitic wasps to control caterpillar pests or introducing nematodes to target specific soil-dwelling pests.
