"Biological control was described by Thompson (1930) as a method of pest control that relies on natural enemies - parasites, predators and pathogens - to reduce pest populations to tolerable levels. Biological control is only a part of integrated control, which also incorporates other methods of pest control including, host plant resistance, cultivation methods, genetic manipulation of pests and moreover selective use of chemicals such as pheromones, hormones and also pesticides (FAO), 1973). In the Netherlands, the Working Group for Integrated Control of Insect Pests, TNO, was established in 1958." . . "Biological Control of Fruit-Tree Red Spider Mite" . . . . . . .
