Biological Pest Control

In some countries, international aid agencies help farmers to increase the yield of their crop. One of the methods that may be used is biological pest control, which is cheaper than using chemical pesticides. Biological control agents might be natural predators or parasites from the local area, or it may be a species that has been introduced.

You will need to carry out some research into how possible organisms are found and also how the benefits and risks of using these organisms are assessed. You can then consider and evaluate the effectiveness of using biological pest control and determine whether biological control alone is effective or whether a combination of biological and chemical pest control is better.
