Abstract

The reason control measures are applied is to reduce the harm caused by pests. “Pests” is a subjective word that is arbitrarily used to refer to some of the living organisms that harm man and his property. Pest control measures may be classified on any of several bases, bur any one classification that uses several bases is liable to cause misunderstandings. Biological controls are the use by man of living organisms to control pest damage. Approaches to biological control are illustrated by results of work on four pests found in Ontario. These results also illustrate how insects may be interrelated through natural enemies that they have in common. As far as possible control measures should be selective for pests, or pest and other non-beneficial, species only. Biological controls tend to be relatively more selective than other, comparable, control measures. They are also the most feasible existing way of keeping pest damage down without continuing human intervention. Increasing attempts to erase pest problems, rather than to alleviate pest attacks temporarily, may result in increased Government participation in and regulation of pest control programmes.
