The “father” of modern biological control, Professor Harry Scott Smith, defined it as the use of natural enemies (whether introduced or otherwise manipulated) to control insect pests.
He was an American entomologist who was a specialist in biological control. He wrote the influential book Biological Control by Natural Enemies first published in 1974 which went through several editions and helped in the development of the field of biological control.
