All the countries of southern Africa have embraced the ecosystem technology of modern biological control (= biocontrol). South Africa is a world leader in research into and application of biocontrol agents against alien invasive plants. A fairly large number of biocontrol agents are also established to combat insect pests of agriculture and forestry. There is even current research on using "good" fungi to combat "bad" fungi.

The successful biological control agents in southern Africa are insects, mites or fungi introduced from other continents.

Biocontrol remains a contentious matter, and there are a couple of regrettable examples of the process having gone awry in the past. Biological control in the 21st century is, however, a meticulous science, particularly where biocontrol of invasive plants is concerned. Much larger numbers of potential biocontrol agents are rejected during rigorous test phases than those select few – proven to be least-hazardous – that are eventually released into the environment.

In southern Africa, biological control contributes an incalculably large positive influence on many different aspects of the environment and of agriculture, horticulture and silviculture. Despite the difficulty of doing so, a number of estimates of the monetary value of biocontrol in southern Africa have been published. Estimates point to environmental and agricultural "savings" of billions of Rand per year.

 
This iSpot Project is tag-driven. All observations of either the biocontrollers themselves, or of the effect of the biocontrollers, should be tagged with   Alien Biocontrol.   They will then automatically display as a collection of related observations here.
