Biological Control Pest Note Revised

Biological control is the beneficial action of predators, parasites, pathogens, and competitors in controlling pests and their damage. Biological control provided by these living organisms (collectively called "natural enemies") is especially important for reducing the numbers of pest insects and mites, but natural enemies can also contribute to the control of weed, pathogen, nematode or vertebrate pests.

In the recently revised Pest Note Biological Control and Natural Enemies of Invertebrates, authored by Steve Dreistadt of the UC Statewide IPM Program, you can learn more about how natural enemies are an important component of any integrated pest management program and how you can identify, encourage, and protect beneficials in your garden and landscape.
