Implementation of biological control
American Journal of Alternative Agriculture, 1988AbstractThe number of species of insect pests, estimated to be maximally 10,000 worldwide, forms only a small part of the millions of species of plant-eating insects. Chemical pest control is becoming increasingly difficult and objectionable in terms of environmental contamination so that other methods of pest control need to be developed.

Abstract Classical biological control attempts from 1921 to 1944 were not effective. During the 1960s, an important success was obtained by controlling the rhodesgrass scale in thousands of hectares of pastures with an introduced parasitoid. Also biocontrol of wheat aphids by introduction of parasitoids and predators appeared effective. Further,

The biological approach, as an integral part of integrated and sustainable weed control approaches, has an increasing importance and consideration due to increasing environmental and anthropogenic problems. Successful weed control through use of biological agents has a background of more than a couple of centuries.

Biological control is any activity taken to prevent, limit, clean up, or remediate potential environmental, health and safety, or workplace quality impacts from plants, animals, or microorganisms. At Hanford the principal emphasis of biological control is to prevent the transport of radioactive contamination by biological vectors (plants, animals, or ...
