Combined Chemical and Biological Control of Insects by Means of a Systemic Insecticide

Article metrics


BIOLOGICAL control as a supplement to chemical control of insect pests was discussed by the first -named author in an article in Nature in 19441. It was shown that there was a practical possibility of utilizing the predators and parasites of a pest species by controlling the pest with a selective insecticide. A selective insecticide was defined as a chemical which is toxic to pests but which does not kill the natural enemies of pests—the predators and parasites.
