| description | Though studies in biological control belong to the best documented research in ecology the actual decision to release a beneficial organism is often influenced by diffuse fears of anything foreign. Yet, agriculture is largely based on exotics; others remain inconspicuous and integrate themselves without problems into the existing ecosystems; and only few actually cause damage. It is against this latter group that the introduction of adapted predators from the region of origin, so-called classical biological control, offers most promise. Here we present four projects from tropical Africa, which were documented throughout all stages from the introduction of predators and parasitoids to the calculations of economic benefits: cassava mealybug, mango mealybug, cassava green mite, and waterhyacinth. Apart from specific conclusions, the high returns of these projects and the various impacts on non-target organisms are discussed. |
