Chapter 4 – BIOLOGICAL CONTROL - Invasive
BIOLOGICAL CONTROL Weed CONTROL Methods Handbook, The Nature Conservancy, Tu et al. John M. Randall and Mandy Tu BIOLOGICAL CONTROL (biocontrol for short) is the use of animals, fungi, or other microbes to feed upon, parasitize or otherwise interfere with a targeted pest species. Successful biocontrol programs usually significantly reduce the abundance of the pest, but in some cases, they simply prevent the damage caused by the pest ( by preventing it from feeding on valued crops) without reducing pest abundance (Lockwood 2000).
